Class ParameterValidator

org.pjdbc.validation.ParameterValidator

public final class ParameterValidator
extends Object

Validates URL parameters against DriverParameter annotations at runtime.

This class provides runtime validation of driver parameters using the same constraints defined in the annotations. It validates:

• Required parameters are present
• Parameter values match the declared type (INTEGER, FLOAT, BOOLEAN, STRING)
• Numeric values are within min/max bounds
• String values are in the declared enum values (if specified)

Example usage:

 Map<String, String> params = getUrlParameters(url);
 ParameterValidator.validate(MyDriver.class, params);
