Annotation Type Constraint

@Documented
 @Target(value=ANNOTATION_TYPE)
 @Retention(value=RUNTIME)
public @interface Constraint

Meta annotation to declare a constraint annotation. Every custom constraint annotation meta-annotated with this very annotation must implement the following fields:

• String message() - the message to be used if this constraint is violated.
• Class<?>[] groups() default {}; - the validation group. See GroupSequence. If a constraint gets applied without any specific group then Default is assumed.
• Class<? extends Payload>[] payload() default {}; - Custom Payload for the contstraint.
