Class Tracer

org.antlr.runtime.debug.BlankDebugEventListener

org.antlr.runtime.debug.Tracer

All Implemented Interfaces:

DebugEventListener

public class Tracer
extends BlankDebugEventListener

The default tracer mimics the traceParser behavior of ANTLR 2.x. This listens for debugging events from the parser and implies that you cannot debug and trace at the same time.
