Used to print out token names like ID during debugging and error reporting. The generated parsers implement a method that overrides this to point to their String[] tokenNames.

Overrides:

getTokenNames in class BaseRecognizer

getGrammarFileName
```
public java.lang.String getGrammarFileName()
```
Description copied from class: BaseRecognizer

For debugging and other purposes, might want the grammar name. Have ANTLR generate an implementation for this method.

Overrides:

getGrammarFileName in class BaseRecognizer

getCurrentRuleName

public java.lang.String getCurrentRuleName()

setCurrentRuleName

public void setCurrentRuleName(java.lang.String value)

getOuterAltNum
```
public int getOuterAltNum()
```

setOuterAltNum

public void setOuterAltNum(int value)

reportError
```
public void reportError(RecognitionException ex)
```
Description copied from class: 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.

Overrides:
