Method Detail

initialize

public abstract void initialize(A constraintAnnotation)

Initialize the validator in preparation for isValid calls. The constraint annotation for a given constraint declaration is passed. This method is guaranteed to be called before any use of this instance for validation.

Specified by:

initialize in interface javax.validation.ConstraintValidator<A extends Annotation,T>

Parameters:

constraintAnnotation - annotation instance for a given constraint declaration

isValid

public abstract boolean isValid(T value,
                                javax.validation.ConstraintValidatorContext context)

Implement the validation logic. The state of value must not be altered. This method can be accessed concurrently, thread-safety must be ensured by the implementation.

Specified by:

isValid in interface javax.validation.ConstraintValidator<A extends Annotation,T>

Parameters:

value - object to validate

context - context in which the constraint is evaluated

Returns:

false if value does not pass the constraint
