All Implemented Interfaces:

org.antlr.runtime.debug.DebugEventListener

public class ParseTokenListener
extends org.antlr.runtime.debug.BlankDebugEventListener

A token processor to render the ANTLR tokens. This token processor is notified as ANTLR parses every token. This processor controls a renderer that renders the token.

Methods

Modifier and Type	Method and Description
void	consumeHiddenToken(org.antlr.runtime.Token token) Hidden tokens are tokens that are not processed at lexical processing stage.
void	consumeToken(org.antlr.runtime.Token token) A regular token is delegated to the renderer for a string representation and the resultant string is sent to the output stream.

Method Detail

enterDecision

public void enterDecision(int d)

Specified by:

enterDecision in interface org.antlr.runtime.debug.DebugEventListener

Overrides:

enterDecision in class org.antlr.runtime.debug.BlankDebugEventListener

exitDecision

public void exitDecision(int i)

Specified by:

exitDecision in interface org.antlr.runtime.debug.DebugEventListener

Overrides:

exitDecision in class org.antlr.runtime.debug.BlankDebugEventListener

consumeToken

public void consumeToken(org.antlr.runtime.Token token)

A regular token is delegated to the renderer for a string representation and the resultant string is sent to the output stream.

Specified by:

consumeToken in interface org.antlr.runtime.debug.DebugEventListener

Overrides:

consumeToken in class org.antlr.runtime.debug.BlankDebugEventListener

consumeHiddenToken

public void consumeHiddenToken(org.antlr.runtime.Token token)

Hidden tokens are tokens that are not processed at lexical processing stage. The most important hidden token for rendering are the tokens that represent multi-line or single line comments. The multi-line comments must be broken into individual lines for line numbering to remain consistent.
