All Implemented Interfaces:

INRLAstVisitor

public class ActionVisitorDispatcher
extends ConstraintVisitorDispatcher

An extension of the basic dispatching AST visitor class that adds action language support.

Implementors of mappings of the full action language, including the base constraint language, should implement this visitor class. For every node in the AST, which is visited in a pre-order traversal, they will get a call to a before method before a node is visited and a call to an after method once its children have been visited.

To use the class, extend and implement all abstract methods.
