Hello, I've this grammar: http://pastebin.com/dNzdGx8R but i get this error when I test it with AntlrWorks:
[11:23:59] /Users/hammer/output/RDFPathParser.java:383: incompatible types [11:23:59] found : RDFPathParser.repeat_return [11:23:59] required: RDFPathParser.shortestPath_return [11:23:59] v=repeat(); [11:23:59] ^ [11:23:59] /Users/hammer/output/RDFPathParser.java:586: incompatible types [11:23:59] found : RDFPathParser.filter_return [11:23:59] required: RDFPathParser.subquery_return [11:23:59] v=filter(); [11:23:59] ^ [11:23:59] 2 errors Basically I think the problem is the assignment in the subrules with ORs in two statements: locationStep: edge condition? (v=repeat | v=shortestPath)? ('>' locationStep)? -> ^(LOCATIONSTEP condition $v locationStep); condition: ( v=filter | v=subquery ) condition? -> ^(CONDITION $v condition); How do I handle these situations where I have the two or more options in a subrule?
