Class Adjunct

java.lang.Object

com.saxonica.ee.pattern.Adjunct

Direct Known Subclasses:

ExpressionADJ, NodeTestADJ, PatternADJ

public abstract class Adjunct
extends Object

Adjuncts for patterns and expressions for use in EE-level optimization. They are a parallel set of classes, which point to the objects they 'enhance' Currently we use three different base classes on top of Adjunct, as, while Patterns are technically Expressions, they are used in pretty different ways.
