public interface LanguageObject
extends java.io.Serializable, java.lang.Cloneable

This is the primary interface for all language objects. It extends a few key interfaces and adds some additional methods to allow the LanguageVisitor to work.

Method Summary

void	acceptVisitor(LanguageVisitor visitor) Method for accepting a visitor.
java.lang.Object	clone() Implement clone to make objects cloneable.

Method Detail

acceptVisitor

void acceptVisitor(LanguageVisitor visitor)

Method for accepting a visitor. It is the responsibility of the language object to call back on the visitor.

Parameters:
