                  extended by at.dms.kjc.JEmittedTextExpression
All Implemented Interfaces:
Constants, DeepCloneable, Finalizable, Serializable

public class JEmittedTextExpression
extends JExpression

The sole purpose of this class is to emit text directly from a compiler backend. Should help to deal with mismatch between kjc and C: sould be able to implement infix expressions ".", "->", prefix expressions "&", "*", surroundfix expressions "sizeof(...)" etc.
