isValid(CharSequence value,
ConstraintValidatorContext constraintValidatorContext)
Implements the validation logic.

public void initialize(Pattern parameters)
ConstraintValidator
ConstraintValidator.isValid(Object, ConstraintValidatorContext)
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.
The default implementation is a no-op.
