Method Detail

getAnnotation

T getAnnotation()

Returns the annotation describing the constraint declaration. If a composing constraint, attribute values are reflecting the overridden attributes of the composing constraint

Returns:

The annotation for this constraint.

getGroups

Set<Class<?>> getGroups()

The set of groups the constraint is applied on. If the constraint declares no group, a set with only the Default group is returned.

Returns:

The groups the constraint is applied on.

getPayload

Set<Class<? extends Payload>> getPayload()

The set of payload the constraint hosts.

Returns:

payload classes hosted on the constraint or an empty set if none.

getConstraintValidatorClasses

List<Class<? extends ConstraintValidator<T,?>>> getConstraintValidatorClasses()

List of the constraint validation implementation classes.

Returns:

list of the constraint validation implementation classes.

getAttributes

Map<String,Object> getAttributes()

Returns a map containing the annotation attribute names as keys and the annotation attribute values as value. If this constraint is used as part of a composed constraint, attribute values are reflecting the overridden attribute of the composing constraint.

Returns:

a map containing the annotation attribute names as keys and the annotation attribute values as value.

getComposingConstraints

Set<ConstraintDescriptor<?>> getComposingConstraints()

Return a set of composing ConstraintDescriptors where each descriptor describes a composing constraint. ConstraintDescriptor instances of composing constraints reflect overridden attribute values in getAttributes() and getAnnotation().

Returns:

a set of ConstraintDescriptor objects or an empty set in case there are no composing constraints.

isReportAsSingleViolation

boolean isReportAsSingleViolation()

Returns:

true if the constraint is annotated with @ReportAsSingleViolation
