void	displayRecognitionError(String[] tokenNames, org.antlr.runtime.RecognitionException e) Creates the error/warning message that we need to show users/IDEs when ANTLR has found a parsing error, has recovered from it and is now telling us that a parsing exception occurred.

Constructor Detail

AbstractParser

protected AbstractParser(org.antlr.runtime.TokenStream input)

AbstractParser

protected AbstractParser(org.antlr.runtime.TokenStream input,
              org.antlr.runtime.RecognizerSharedState state)

Create a new parser instance, pre-supplying the input token stream and the shared state.

This is only used when a grammar is imported into another grammar, but we must supply this constructor to satisfy the super class contract.

Parameters:

input - The stream of tokesn that will be pulled from the lexer

state - The shared state object created by an interconnectd grammar

Method Detail

displayRecognitionError

public void displayRecognitionError(String[] tokenNames,
                           org.antlr.runtime.RecognitionException e)

Creates the error/warning message that we need to show users/IDEs when ANTLR has found a parsing error, has recovered from it and is now telling us that a parsing exception occurred.

Overrides:

displayRecognitionError in class org.antlr.runtime.BaseRecognizer

Parameters:

tokenNames - token names as known by ANTLR (which we ignore)

e - The exception that was thrown

load

public static void load(InputStream in,
        Proto proto)
                 throws Exception

Throws:

Exception
