All Known Implementing Classes:

public interface ConstraintPredicate
extends Serializable

A predicate defines a single boolean operation on an Annotation or some property of an annotation. These are also referred to as attributes of a constraint.

Implementors will determine if a provided annotation matches the predicate based on the intent of the operator (equals, not equals, greater than, etc).
