Think of it as SQL for your hierarchical data structures, but with the flexibility of both programmatic method chaining and declarative XPath-like syntax. + +The system addresses a common challenge in hierarchical data management: how to efficiently find, filter, and extract specific nodes or properties from deeply nested structures without writing verbose traversal code. DataTreeQuery solves this by providing two complementary approaches: + +- **Fluent API**: Method chaining that reads like natural language and provides full IDE support with autocompletion +- **XPath-like syntax**: Familiar string-based queries for developers comfortable with XML/HTML querying + +Both approaches benefit from lazy evaluation, meaning queries are built up as lightweight operation chains and only executed when you actually need the results. This provides excellent performance characteristics, especially for complex queries that might not need to examine the entire tree. + +### Getting Started with DataTreeQuery + +Before diving into query examples, let's establish a realistic DataTree structure that represents a typical GUI application. This will serve as our playground for exploring DataTreeQuery capabilities. + +```cpp +// Sample DataTree structure for examples +DataTree appRoot("Application"); +{ + auto tx = appRoot.beginTransaction("Create sample structure"); + + // Add buttons + DataTree saveButton("Button"); + { + auto saveTx = saveButton.beginTransaction("Setup save button"); + saveTx.setProperty("text", "Save"); + saveTx.setProperty("enabled", true); + saveTx.setProperty("x", 10); + saveTx.setProperty("y", 20); + } + + DataTree loadButton("Button"); + { + auto loadTx = loadButton.beginTransaction("Setup load button"); + loadTx.setProperty("text", "Load"); + loadTx.setProperty("enabled", false); + loadTx.setProperty("x", 10); + loadTx.setProperty("y", 60); + } + + // Add panels + DataTree leftPanel("Panel"); + { + auto leftTx = leftPanel.beginTransaction("Setup left panel"); + leftTx.setProperty("name", "LeftPanel"); + leftTx.setProperty("width", 200); + leftTx.setProperty("docked", true); + leftTx.addChild(saveButton); + leftTx.addChild(loadButton); + } + + DataTree rightPanel("Panel"); + { + auto rightTx = rightPanel.beginTransaction("Setup right panel"); + rightTx.setProperty("name", "RightPanel"); + rightTx.setProperty("width", 150); + rightTx.setProperty("docked", false); + } + + // Add main window + DataTree mainWindow("Window"); + { + auto windowTx = mainWindow.beginTransaction("Setup window"); + windowTx.setProperty("title", "My Application"); + windowTx.setProperty("width", 800); + windowTx.setProperty("height", 600); + windowTx.setProperty("visible", true); + windowTx.addChild(leftPanel); + windowTx.addChild(rightPanel); + } + + tx.addChild(mainWindow); + + // Add settings dialog + DataTree settingsDialog("Dialog"); + { + auto dialogTx = settingsDialog.beginTransaction("Setup dialog"); + dialogTx.setProperty("title", "Settings"); + dialogTx.setProperty("modal", true); + dialogTx.setProperty("visible", false); + } + + tx.addChild(settingsDialog); +} +``` + +This sample structure creates a realistic hierarchy with windows, panels, buttons, and dialogs - each with relevant properties like dimensions, states, and identifiers. Notice how we use transactions to build the structure safely, following DataTree best practices. + +### Basic Fluent API Queries + +The fluent API is DataTreeQuery's most intuitive interface, allowing you to chain method calls in a way that reads almost like English. Each method returns a DataTreeQuery object, enabling smooth composition of complex queries. + +Let's start with simple queries that demonstrate the core concepts: + +```cpp +// Find all buttons in the application +auto allButtons = DataTreeQuery::from(appRoot) + .descendants("Button") + .nodes(); + +DBG("Found " << allButtons.size() << " buttons"); + +// Find enabled buttons only +auto enabledButtons = DataTreeQuery::from(appRoot) + .descendants("Button") + .where([](const DataTree& node) { + return node.getProperty("enabled", false); + }) + .nodes(); + +// Get the first enabled button +auto firstEnabledButton = DataTreeQuery::from(appRoot) + .descendants("Button") + .where([](const DataTree& node) { + return node.getProperty("enabled", false); + }) + .first() + .node(); + +if (firstEnabledButton.isValid()) +{ + DBG("First enabled button: " << firstEnabledButton.getProperty("text").toString()); +} +``` + +These examples show the fundamental pattern: start with `DataTreeQuery::from()`, add filtering or navigation operations, and terminate with a result extraction method like `nodes()` or `node()`. The `where()` method accepts any predicate function, giving you complete flexibility in defining your filtering logic. + +Notice how we check `isValid()` on individual nodes - this is important because query operations can return invalid DataTree objects when no matches are found, similar to how database queries might return null results. + +### Navigation and Traversal + +DataTree navigation is one of DataTreeQuery's strongest features. Unlike manual tree traversal which requires recursive functions and careful null checking, DataTreeQuery provides declarative methods that handle all the complexity internally. + +The navigation methods mirror common tree traversal patterns: + +```cpp +// Find all direct children of the main window +auto windowChildren = DataTreeQuery::from(appRoot) + .descendants("Window") + .first() + .children() + .nodes(); + +// Find all panels in the application +auto panels = DataTreeQuery::from(appRoot) + .descendants("Panel") + .nodes(); + +// Find parent window of buttons +auto buttonParents = DataTreeQuery::from(appRoot) + .descendants("Button") + .parent() + .distinct() // Remove duplicates + .nodes(); + +// Find siblings of the first button +auto firstButton = DataTreeQuery::from(appRoot) + .descendants("Button") + .first() + .node(); + +if (firstButton.isValid()) +{ + auto siblings = DataTreeQuery::from(firstButton) + .siblings() + .nodes(); + DBG("Button has " << siblings.size() << " siblings"); +} +``` + +Navigation methods can be chained freely - you might find all buttons, navigate to their parents, then find siblings of those parents. The `distinct()` method is particularly useful when navigation might produce duplicate nodes, ensuring clean result sets. + +The `siblings()` method is especially handy for UI applications where you need to find related controls at the same hierarchical level, such as buttons in the same toolbar or panels in the same container. + +### Property-Based Filtering + +Property-based filtering is where DataTreeQuery really shines for application data. Most real-world queries aren't just about structure ("find all buttons") but about data ("find all enabled buttons with specific text"). + +DataTreeQuery provides several specialized methods that make property-based queries both efficient and readable: + +```cpp +// Find nodes with specific properties +auto namedPanels = DataTreeQuery::from(appRoot) + .descendants("Panel") + .hasProperty("name") + .nodes(); + +// Find panels with specific names +auto leftPanels = DataTreeQuery::from(appRoot) + .descendants("Panel") + .propertyEquals("name", "LeftPanel") + .nodes(); + +// Find wide panels (width > 180) +auto widePanels = DataTreeQuery::from(appRoot) + .descendants("Panel") + .propertyWhere("width", [](int width) { + return width > 180; + }) + .nodes(); + +// Find non-docked panels +auto floatingPanels = DataTreeQuery::from(appRoot) + .descendants("Panel") + .propertyNotEquals("docked", true) + .nodes(); +``` + +These property filtering methods are designed to be composable - you can chain multiple property conditions to create complex filters. The `propertyWhere()` method is particularly powerful because it provides type-safe access to property values, automatically handling the conversion from `var` to your desired type. + +For numeric comparisons, `propertyWhere()` is often more readable than using XPath syntax, especially when the logic becomes complex or when you need to call other C++ functions within the predicate. + +### Property Extraction and Transformation + +Often, you don't want the DataTree nodes themselves, but rather specific properties or computed values derived from those nodes. DataTreeQuery's transformation system handles this elegantly, converting node-based queries into property-based or computed results. + +The transformation system works in two stages: selection (what to extract) and conversion (how to format the results): + +```cpp +// Extract button texts +auto buttonTexts = DataTreeQuery::from(appRoot) + .descendants("Button") + .property("text") + .strings(); + +for (const String& text : buttonTexts) +{ + DBG("Button text: " << text); +} + +// Extract multiple properties from windows +auto windowProps = DataTreeQuery::from(appRoot) + .descendants("Window") + .properties({"title", "width", "height"}) + .properties(); // Returns std::vector + +// Transform nodes to custom format +auto buttonInfo = DataTreeQuery::from(appRoot) + .descendants("Button") + .select([](const DataTree& button) { + return button.getProperty("text").toString() + + " (" + String(button.getProperty("enabled", false) ? "enabled" : "disabled") + ")"; + }) + .strings(); + +for (const String& info : buttonInfo) +{ + DBG("Button info: " << info); +} +``` + +Property extraction is particularly useful for data binding scenarios - you can extract button labels for populating lists, configuration values for initializing components, or any other property-based data your application needs. + +The `select()` transformation method is incredibly powerful, allowing you to compute derived values, format strings, or even create complex data structures from your DataTree nodes. Think of it as the "SELECT" clause in SQL, but with the full power of C++ lambda expressions. + +### Ordering and Pagination + +Large hierarchical structures often need sorting and pagination to be manageable. DataTreeQuery provides comprehensive ordering capabilities that work seamlessly with all other query operations. + +Sorting can be based on properties, computed values, or any comparable criteria: + +```cpp +// Sort buttons by their text +auto sortedButtons = DataTreeQuery::from(appRoot) + .descendants("Button") + .orderByProperty("text") + .nodes(); + +// Sort panels by width (custom ordering) +auto sortedPanels = DataTreeQuery::from(appRoot) + .descendants("Panel") + .orderBy([](const DataTree& panel) { + return panel.getProperty("width", 0); + }) + .nodes(); + +// Get first 3 nodes, skip first 2 +auto paginatedResults = DataTreeQuery::from(appRoot) + .descendants() + .skip(2) + .take(3) + .nodes(); + +// Get specific positions +auto specificNodes = DataTreeQuery::from(appRoot) + .descendants("Button") + .at({0, 2}) // First and third buttons + .nodes(); + +// Get last button +auto lastButton = DataTreeQuery::from(appRoot) + .descendants("Button") + .last() + .node(); +``` + +The ordering methods return sorted results while maintaining all DataTree relationships and properties. This is particularly useful for UI applications where you need to display hierarchical data in a specific order - sorted by name, priority, creation date, or any other criteria. + +Pagination methods (`skip()`, `take()`, `at()`) are essential for performance when dealing with large data sets. Instead of retrieving thousands of nodes and processing them in your application code, you can limit the query results at the source. + +### XPath-Like String Queries + +For developers familiar with XPath from XML/HTML processing, DataTreeQuery offers a familiar string-based syntax that maps XPath concepts to DataTree structures. This approach is particularly valuable for: + +- **Configuration-driven queries**: Store query strings in config files or databases +- **Dynamic queries**: Build query strings programmatically based on user input +- **Rapid prototyping**: Quick exploration of data structures without writing full C++ code +- **Domain-specific languages**: Building query interfaces for non-programmers + +The XPath syntax in DataTreeQuery covers the most commonly used XPath features, adapted for DataTree semantics: + +```cpp +// Basic descendant selection +auto buttons = DataTreeQuery::xpath(appRoot, "//Button").nodes(); + +// Property-based filtering +auto enabledButtons = DataTreeQuery::xpath(appRoot, "//Button[@enabled='true']").nodes(); +auto namedPanels = DataTreeQuery::xpath(appRoot, "//Panel[@name]").nodes(); + +// Property extraction +auto buttonTexts = DataTreeQuery::xpath(appRoot, "//Button/@text").strings(); +auto dialogTitles = DataTreeQuery::xpath(appRoot, "//Dialog/@title").strings(); + +// Position-based selection +auto firstButton = DataTreeQuery::xpath(appRoot, "//Button[1]").node(); // 1-indexed +auto lastPanel = DataTreeQuery::xpath(appRoot, "//Panel[last()]").node(); +auto firstTwoButtons = DataTreeQuery::xpath(appRoot, "//Button[position() <= 2]").nodes(); + +// Complex conditions +auto modalDialogs = DataTreeQuery::xpath(appRoot, + "//Dialog[@modal='true' and @visible='false']").nodes(); + +// Text content access +auto buttonLabels = DataTreeQuery::xpath(appRoot, "//Button/text()").strings(); + +// Comparison operators +auto widePanels = DataTreeQuery::xpath(appRoot, "//Panel[@width > 180]").nodes(); +auto enabledButtons = DataTreeQuery::xpath(appRoot, "//Button[@enabled != 'false']").nodes(); + +// Sibling axis navigation +auto nextButtons = DataTreeQuery::xpath(appRoot, "//Button[@text='Save']/following-sibling").nodes(); +auto prevPanels = DataTreeQuery::xpath(appRoot, "//Panel[@name='RightPanel']/preceding-sibling").nodes(); +``` + +XPath queries are particularly elegant for simple, well-defined queries. The property extraction syntax (`/@propertyName`) is often more concise than the equivalent fluent API calls, especially when you're extracting the same property from many nodes. + +Position-based predicates like `[1]` and `[last()]` are invaluable for UI queries where you need specific items from lists - the first button in a toolbar, the last panel in a layout, or the second dialog in a stack. + +### Advanced XPath Syntax Reference + +Understanding the full XPath syntax available in DataTreeQuery helps you write more sophisticated queries. Here's a comprehensive reference with explanations of when each feature is most useful: + +```cpp +// Axis and path expressions +"//NodeType" // All descendants of type NodeType +"/NodeType" // Direct children of type NodeType +"*" // Any node type +"." // Current node +".." // Parent node +"/following-sibling" // All following sibling nodes +"/preceding-sibling" // All preceding sibling nodes + +// Property predicates +"[@property]" // Nodes with property +"[@property='value']" // Property equals value +"[@property!='value']" // Property not equals value +"[@property > 100]" // Numeric comparison (>, <, >=, <=) + +// Position predicates +"[1]" // First child (1-indexed) +"[2]" // Second child +"[first()]" // First child +"[last()]" // Last child +"[position() > 2]" // Position greater than 2 + +// Logical operators +"[@a='x' and @b='y']" // Both conditions +"[@a='x' or @b='y']" // Either condition +"[not(@disabled)]" // Negation + +// Functions +"text()" // Text content +"count()" // Count of nodes +``` + +This syntax reference shows how DataTreeQuery maps XPath concepts to DataTree operations. The position-based predicates are 1-indexed (following XPath convention), while the fluent API uses 0-based indexing (following C++ convention). + +Logical operators (`and`, `or`, `not()`) enable complex filtering that would be verbose with multiple fluent API calls. Functions like `text()` provide semantic access to common data patterns. + +### Combining Fluent API with XPath + +One of DataTreeQuery's most powerful features is the ability to seamlessly mix fluent API calls with XPath strings within the same query. This hybrid approach lets you use the best tool for each part of your query: + +- Use fluent API for complex programmatic logic and IDE support +- Use XPath for simple, well-defined patterns and configuration-driven queries + +The combination is particularly effective for building reusable query components: + +```cpp +// Start with fluent API, then use XPath +auto complexQuery = DataTreeQuery::from(appRoot) + .descendants("Window") + .xpath(".//Button[@enabled='true']") // XPath on current selection + .orderByProperty("text") + .take(5) + .nodes(); + +// Mix and match approaches +auto mixedQuery = DataTreeQuery::from(appRoot) + .xpath("//Panel[@docked='true']") // XPath to find docked panels + .children() // Fluent API to get children + .ofType("Button") // Filter to buttons only + .where([](const DataTree& btn) { // Custom predicate + return btn.getProperty("text").toString().startsWith("S"); + }) + .nodes(); +``` + +This hybrid approach is especially valuable in larger applications where different parts of the query might be maintained by different team members, or where part of the query logic needs to be configurable while other parts require programmatic flexibility. + +The `.xpath()` method can be called on any DataTreeQuery object, applying the XPath expression to the current selection rather than starting from the root. This enables powerful composition patterns. + +### Grouping and Aggregation + +While DataTreeQuery excels at finding and filtering individual nodes, real applications often need to analyze patterns across collections of nodes. The grouping system provides SQL-like GROUP BY functionality for hierarchical data. + +Grouping is particularly useful for: + +```cpp +// Group buttons by their enabled state +auto buttonsByState = DataTreeQuery::from(appRoot) + .descendants("Button") + .groupBy([](const DataTree& button) { + return button.getProperty("enabled", false) ? "enabled" : "disabled"; + }); + +for (const auto& [state, buttons] : buttonsByState) +{ + DBG(state.toString() << ": " << buttons.size() << " buttons"); +} + +// Group panels by width ranges +auto panelsBySize = DataTreeQuery::from(appRoot) + .descendants("Panel") + .groupBy([](const DataTree& panel) { + int width = panel.getProperty("width", 0); + if (width < 150) return var("small"); + if (width < 250) return var("medium"); + return var("large"); + }); +``` + +Grouping creates a map where keys represent the grouping criteria and values contain vectors of nodes that match that criteria. This is incredibly useful for categorizing UI elements, analyzing configuration patterns, or building summary reports from hierarchical data. + +The grouping key can be any value that's convertible to `var` - strings, numbers, booleans, or even complex computed values. This flexibility enables sophisticated analytical queries. + +### Conditional Operations + +Sometimes you don't need the actual data, but rather answers to questions about the data: "Are there any disabled buttons?" or "Do all panels have names?" DataTreeQuery provides efficient conditional operations that can answer these questions without building complete result sets. + +```cpp +// Check if any buttons are disabled +bool hasDisabledButtons = DataTreeQuery::from(appRoot) + .descendants("Button") + .any([](const DataTree& button) { + return !button.getProperty("enabled", true); + }); + +// Check if all panels are docked +bool allPanelsDocked = DataTreeQuery::from(appRoot) + .descendants("Panel") + .all([](const DataTree& panel) { + return panel.getProperty("docked", false); + }); + +// Find first button with specific text +auto saveButton = DataTreeQuery::from(appRoot) + .descendants("Button") + .firstWhere([](const DataTree& button) { + return button.getProperty("text").toString() == "Save"; + }); + +// Count matching elements +int enabledButtonCount = DataTreeQuery::from(appRoot) + .descendants("Button") + .where([](const DataTree& button) { + return button.getProperty("enabled", false); + }) + .count(); +``` + +These conditional operations are optimized for early termination - `any()` stops as soon as it finds one matching element, and `all()` stops as soon as it finds one non-matching element. This makes them much more efficient than retrieving all results and checking them in application code. + +The `firstWhere()` method combines filtering and selection, returning the first node that matches your criteria. This is often more efficient than filtering all nodes and then selecting the first result. + +### Performance Considerations + +DataTreeQuery's lazy evaluation system is designed to minimize unnecessary work, but understanding how it works helps you write more efficient queries. The key insight is that DataTreeQuery builds operation chains without executing them until you request actual results. + +This lazy approach provides several performance benefits: + +```cpp +// Lazy evaluation - query is built but not executed +DataTreeQuery query = DataTreeQuery::from(appRoot) + .descendants("Button") + .where([](const DataTree& node) { return expensiveCheck(node); }); + +// Execution only happens when results are accessed +if (query.any()) // Executes query and stops at first match +{ + auto results = query.nodes(); // Re-executes query for full results +} + +// Cache results for multiple accesses +auto result = DataTreeQuery::from(appRoot) + .descendants("Button") + .execute(); // Explicit execution + +// Multiple accesses to same result are efficient +auto nodes = result.nodes(); +auto count = result.size(); +bool hasResults = !result.empty(); + +// Use early termination for existence checks +bool hasEnabledButtons = DataTreeQuery::from(appRoot) + .descendants("Button") + .where([](const DataTree& btn) { return btn.getProperty("enabled", false); }) + .any(); // Stops at first match +``` + +The most important performance principle is to use the right result extraction method for your needs. If you only need to know whether results exist, use `any()` rather than `nodes().empty()`. If you only need the count, use `count()` rather than `nodes().size()`. + +For complex queries that will be used multiple times, consider caching the `QueryResult` object rather than re-executing the entire query. The `execute()` method gives you explicit control over when evaluation happens. + +### Error Handling and Validation + +Robust applications need to handle edge cases gracefully. DataTreeQuery is designed to be forgiving - it returns empty results rather than throwing exceptions for most error conditions, making it safe to use in production code without extensive error handling. + +However, there are still important validation patterns to follow: + +```cpp +// XPath syntax errors are handled gracefully +auto result = DataTreeQuery::xpath(appRoot, "//Invalid[Syntax"); +if (result.empty()) +{ + DBG("Query returned no results (possibly due to syntax error)"); +} + +// Check for valid results +auto buttons = DataTreeQuery::from(appRoot).descendants("Button").nodes(); +if (buttons.empty()) +{ + DBG("No buttons found"); +} +else +{ + DBG("Found " << buttons.size() << " buttons"); +} + +// Safe property access +auto buttonTexts = DataTreeQuery::from(appRoot) + .descendants("Button") + .where([](const DataTree& btn) { + return btn.hasProperty("text"); // Ensure property exists + }) + .property("text") + .strings(); +``` + +The key to robust DataTreeQuery usage is defensive programming - always check for empty results before using them, validate that properties exist before accessing them, and use appropriate default values when data might be missing. + +XPath syntax errors (malformed expressions) are handled gracefully by returning empty results, but it's still good practice to validate complex XPath strings, especially if they come from external sources. + +### Summary + +DataTreeQuery transforms hierarchical data access from a tedious, error-prone manual process into an expressive, efficient querying system. By providing both programmatic and declarative interfaces, it accommodates different development styles and use cases while maintaining consistent performance characteristics. + +The combination of lazy evaluation, comprehensive filtering options, and seamless API integration makes DataTreeQuery an essential tool for any application working with complex hierarchical data. Whether you're building UI frameworks, configuration systems, or data processing pipelines, DataTreeQuery provides the abstraction layer that makes hierarchical data feel as natural to work with as relational databases. + +Key advantages of adopting DataTreeQuery in your applications: + +- **Reduced boilerplate**: Eliminate manual tree traversal code +- **Improved readability**: Queries read like natural language descriptions of what you want +- **Better performance**: Lazy evaluation and early termination optimize execution +- **Fewer bugs**: Declarative queries are less prone to off-by-one errors and null pointer exceptions +- **Enhanced maintainability**: Changes to data structure require minimal query updates +- **Flexible approaches**: Choose between fluent API and XPath based on the situation + +As your DataTree structures grow in complexity, DataTreeQuery grows with them, providing the tools you need to efficiently access and manipulate hierarchical data at any scale. + +## DataTreeSchema - Validation and Structure + +DataTreeSchema provides JSON Schema-based validation for DataTree structures, ensuring data integrity and enabling smart defaults. + +### Creating Schemas + +Now that we've explored the powerful querying capabilities of DataTreeQuery, let's examine how DataTreeSchema brings structure and validation to our hierarchical data. + +```cpp +// DataTreeSchema uses JSON Schema syntax to define the structure, +// validation rules, and default values for DataTree hierarchies. +// This approach provides a familiar, standardized way to describe +// data constraints that can be shared across languages and tools. + +// Define schema in JSON +String schemaJson = R"({ + "nodeTypes": { + "AppSettings": { + "description": "Application configuration root", + "properties": { + "version": { + "type": "string", + "required": true, + "default": "1.0.0", + "pattern": "^\\d+\\.\\d+\\.\\d+$" + }, + "theme": { + "type": "string", + "default": "light", + "enum": ["light", "dark", "auto"] + }, + "fontSize": { + "type": "number", + "default": 12, + "minimum": 8, + "maximum": 72 + }, + "features": { + "type": "array", + "description": "Enabled feature flags" + } + }, + "children": { + "allowedTypes": ["ServerConfig", "UIConfig"], + "maxCount": 10 + } + }, + "ServerConfig": { + "properties": { + "port": { + "type": "number", + "default": 8080, + "minimum": 1, + "maximum": 65535 + }, + "hostname": { + "type": "string", + "default": "localhost" + } + }, + "children": { + "maxCount": 0 + } + } + } +})"; + +// Load schema +auto schema = DataTreeSchema::fromJsonSchemaString(schemaJson); +if (!schema) +{ + DBG("Failed to load schema"); + return; +} +``` + +### Schema-Driven Node Creation + +```cpp +// Create nodes with defaults applied automatically +auto appSettings = schema->createNode("AppSettings");

+DBG("Max children: " << childConstraints.maxCount); +DBG("Allowed child types: " << childConstraints.allowedTypes.size()); +``` + +### Validated Transactions + +```cpp +// Schema-validated transactions prevent invalid data +auto settings = schema->createNode("AppSettings"); +auto transaction = settings.beginTransaction(schema, "Update settings"); + +// Valid operations +auto result1 = transaction.setProperty("theme", "dark"); // Valid enum +EXPECT_TRUE(result1.wasOk());

+if (childResult.wasOk()) +{ + DataTree server = childResult.getValue(); + // server has all default properties set +} + +// Transaction only commits if all operations were valid +``` + +### Complete Tree Validation + +```cpp +// Validate entire tree structure +auto validationResult = schema->validate(appSettings); +if (validationResult.failed()) +{ + DBG("Validation failed: " << validationResult.getErrorMessage()); + // Handle validation errors +} +else +{ + DBG("Tree structure is valid"); + // Safe to proceed with application logic +} +``` + +## CachedValue - Reactive Properties + +CachedValue provides efficient, cached access to DataTree properties with automatic invalidation when the underlying data changes. + +### Basic Usage + +```cpp +class AppComponent +{ +public: + AppComponent(const DataTree& settingsTree) + : settings(settingsTree) + , theme(settingsTree, "theme", "light") // Property with default + , fontSize(settingsTree, "fontSize", 12) // Numeric property + , isEnabled(settingsTree, "enabled", true) // Boolean property + { + } + + void updateTheme() + { + // Reading from CachedValue is fast (cached) + String currentTheme = theme.get();
