Instance Method Details

#recover(recognizer, e) ⇒ Object

Instead of recovering from exception e, re-throw it wrapped

in a {@link ParseCancellationException} so it is not caught by the
rule function catches.  Use {@link Exception#getCause()} to get the
original {@link RecognitionException}.

Raises:

def recover(recognizer, e)
    context = recognizer.ctx
    while not context.nil?  do
        context.exception = e
        context = context.parentCtx
    end
    raise ParseCancellationException.new(e)
end

#recoverInline(recognizer) ⇒ Object

Make sure we don’t attempt to recover inline; if the parser

successfully recovers, it won't throw an exception.

#sync(recognizer) ⇒ Object

Make sure we don’t attempt to recover from problems in subrules.#
