Class BaseVisitor

java.lang.Object
  org.apache.velocity.runtime.visitor.BaseVisitor

All Implemented Interfaces:

ParserVisitor

Direct Known Subclasses:

NodeViewMode, VMReferenceMungeVisitor

public abstract class BaseVisitor
extends Object
implements ParserVisitor

This is the base class for all visitors. For each AST node, this class will provide a bare-bones method for traversal.
