Validating

The Herrera\Version\Validator class is meant to be used indirectly through the other classes. However, you may use it to validate version information according to the Semantic Versioning specification:

• bool isIdentifier(str $identifier) — returns true if the identifier is valid, false if not. An identifier may belong to either a pre-release version number or build metadata
• bool isNumber(int|str $number) — returns true if the version number is valid, or false if not
• bool isVersion(str $version) — returns true if the string is a valid version string representation, false if not
