Class MetaConstraint<A extends java.lang.annotation.Annotation>

java.lang.Object
  org.hibernate.validator.metadata.MetaConstraint<A>

Direct Known Subclasses:

BeanMetaConstraint, MethodMetaConstraint

public abstract class MetaConstraint<A extends java.lang.annotation.Annotation>
extends java.lang.Object

Instances of this class abstract the constraint type (class, method or field constraint) and give access to meta data about the constraint. This allows a unified handling of constraints in the validator implementation.

The location at which this constraint is defined.

Constructor Detail

MetaConstraint

public MetaConstraint(ConstraintDescriptorImpl<A> constraintDescriptor,
                      ConstraintLocation location)

Parameters:

constraintDescriptor - The constraint descriptor for this constraint

location - meta data about constraint placement

Method Detail

getGroupList

public final java.util.Set<java.lang.Class<?>> getGroupList()

Returns:

Returns the list of groups this constraint is part of. This might include the default group even when it is not explicitly specified, but part of the redefined default group list of the hosting bean.
