Examples of org.antlr.v4.runtime.BailErrorStrategy

org.antlr.v4.runtime.ParserRuleContext
This implementation of {@link ANTLRErrorStrategy} responds to syntax errorsby immediately canceling the parse operation with a {@link ParseCancellationException}. The implementation ensures that the {@link ParserRuleContext#exception} field is set for all parse tree nodesthat were not completed prior to encountering the error.
This error strategy is useful in the following scenarios.
- Two-stage parsing: This error strategy allows the first stage of two-stage parsing to immediately terminate if an error is encountered, and immediately fall back to the second stage. In addition to avoiding wasted work by attempting to recover from errors here, the empty implementation of {@link BailErrorStrategy#sync} improves the performance ofthe first stage.
- Silent validation: When syntax errors are not being reported or logged, and the parse result is simply ignored if errors occur, the {@link BailErrorStrategy} avoids wasting work on recovering from errorswhen the result will be ignored either way.
{@code myparser.setErrorHandler(new BailErrorStrategy());}
@see Parser#setErrorHandler(ANTLRErrorStrategy)

        // add custom error listener that logs syntax errors
        parser.addErrorListener(mErrorListener);


        // This strategy stops parsing when parser error occurs.
        // By default it uses Error Recover Strategy which is slow and useless.
        parser.setErrorHandler(new BailErrorStrategy());
