Method Detail

initialize

public void initialize(EAN constraintAnnotation)

Description copied from interface: ConstraintValidator

Initializes the validator in preparation for 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.

Specified by:

initialize in interface ConstraintValidator<EAN,CharSequence>

Parameters:

constraintAnnotation - annotation instance for a given constraint declaration

isValid

public boolean isValid(CharSequence value,
                       ConstraintValidatorContext context)

Description copied from interface: ConstraintValidator

Implements 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 ConstraintValidator<EAN,CharSequence>

Parameters:

value - object to validate

context - context in which the constraint is evaluated

Returns:

false if value does not pass the constraint
