public class AbstractParseTreeVisitor
extends java.lang.Object
implements ParseTreeVisitor

This class implements a base class visitor for parse trees in the expression language. Primarily this class exists to give nice error messages for visitors that are partly implemented, and to allow us to extend the expression language without completely breaking existing code.

Return an exception that describes an unsupported node type.

Parameters:

name - The name of the node type.

Returns:

An exception that describes an unsupported node type.

_visitAllChildren

protected void _visitAllChildren(ASTPtRootNode node)
                          throws IllegalActionException

Loop through all of the children of this node, visiting each one of them, which will cause their token value to be determined.

Parameters:

node - The node whose children are to be looped through.

Throws:
