python3 Parser.setErrorHandler method missing

I'm trying to bail out of the parser upon first syntax error. It seems that the setErrorHandler is not implemented? This is the error.

 parser.setErrorHandler(BailErrorStrategy())

AttributeError: 'XParser' object has no attribute 'setErrorHandler'

It looks like Python's Parser class does not have a set-ter for this. Don't know why not.

Anyway, this is how you could set it:

from antlr4.error.ErrorStrategy import BailErrorStrategy

...

parser = ...
parser._errHandler = BailErrorStrategy()
