dbg

protected DebugEventListener dbg

Who to notify when events in the parser occur.

isCyclicDecision

public boolean isCyclicDecision

Used to differentiate between fixed lookahead and cyclic DFA decisions while profiling.

构造器详细资料

DebugParser

public DebugParser(TokenStream input,
                   DebugEventListener dbg,
                   RecognizerSharedState state)

Create a normal parser except wrap the token stream in a debug proxy that fires consume events.

DebugParser

public DebugParser(TokenStream input,
                   RecognizerSharedState state)

DebugParser

public DebugParser(TokenStream input,
                   DebugEventListener dbg)

方法详细资料

setDebugListener

public void setDebugListener(DebugEventListener dbg)

Provide a new debug event listener for this parser. Notify the input stream too that it should send events to this listener.

getDebugListener

public DebugEventListener getDebugListener()

reportError

public void reportError(java.io.IOException e)

beginResync

public void beginResync()

从类复制的说明: BaseRecognizer

A hook to listen in on the token consumption during error recovery. The DebugParser subclasses this to fire events to the listenter.

覆盖:

beginResync 在类中 BaseRecognizer

endResync

public void endResync()

覆盖:

endResync 在类中 BaseRecognizer

beginBacktrack

public void beginBacktrack(int level)

endBacktrack

public void endBacktrack(int level,
                         boolean successful)

reportError

public void reportError(RecognitionException e)

从类复制的说明: BaseRecognizer

Report a recognition problem. This method sets errorRecovery to indicate the parser is recovering not parsing. Once in recovery mode, no errors are generated. To get out of recovery mode, the parser must successfully match a token (after a resync). So it will go: 1. error occurs 2. enter recovery mode, report error 3. consume until token found in resynch set 4. try to resume parsing 5. next match() will reset errorRecovery mode If you override, make sure to update syntaxErrors if you care about that.

覆盖:

reportError 在类中 BaseRecognizer
