Class Constraint

java.lang.Object
  gate.jape.Constraint

All Implemented Interfaces:

JapeConstants, Serializable, Cloneable

public class Constraint
extends Object
implements JapeConstants, Serializable, Cloneable

An individual annotation/attribute/value expression. It doesn't extend PatternElement, even though it has to "match", because a set of Constraint must be applied together in order to avoid doing separate selectAnnotations calls for each one.

clone

public Object clone()

Need cloning for processing of macro references. See comments on PatternElement.clone()

Overrides:

clone in class Object
