Class ConstraintTree<A extends Annotation>

java.lang.Object

org.hibernate.validator.internal.engine.constraintvalidation.ConstraintTree<A>

public abstract class ConstraintTree<A extends Annotation>
extends Object

Due to constraint composition a single constraint annotation can lead to a whole constraint tree being validated. This class encapsulates such a tree.
