How to use the qface.idl.parser.TParser.TParser.EnumMemberSymbolContext function in qface

def enumMemberSymbol(self):

        localctx = TParser.EnumMemberSymbolContext(self, self._ctx, self.state)
        self.enterRule(localctx, 50, self.RULE_enumMemberSymbol)

        try:
            self.enterOuterAlt(localctx, 1)

                localctx.comment = self.match(TParser.DOCCOMMENT)
