      org.apache.velocity.runtime.visitor.VMReferenceMungeVisitor

All Implemented Interfaces:

ParserVisitor

public class VMReferenceMungeVisitor
extends BaseVisitor

This class is a visitor used by the VM proxy to change the literal representation of a reference in a VM. The reason is to preserve the 'render literal if null' behavior w/o making the VMProxy stuff more complicated than it is already.
