Interface ParserVisitor

All Known Implementing Classes:

DeepCopyVisitor, DoNothingVisitor, ExpressionConsolidator, FastEvaluator, PrintVisitor, StandardEvaluator, SubstitutionVisitor

public interface ParserVisitor

Classes which wish to use the visitor pattern should use this interface. To use the visitor pattern a class should call Node.jjtAccept(ParserVisitor, Object) which will redirect to one of the methods below. To tranverse the whole tree the visit(ASTFunNode, Object) and visit(ASTFunNode, Object) should also call jjtAccept on each of their children.

Method Summary

java.lang.Object	visit(ASTConstant node, java.lang.Object data)
java.lang.Object	visit(ASTFunNode node, java.lang.Object data)
java.lang.Object	visit(ASTOpNode node, java.lang.Object data)
java.lang.Object	visit(ASTVarNode node, java.lang.Object data)
