    if (node.resolver.resolveToAttribute(x.getText(), node) == null) {
        ErrorType errorType = ErrorType.UNKNOWN_SIMPLE_ATTRIBUTE;
        if (node.resolver.resolvesToListLabel(x.getText(), node)) {
            // $ids for ids+=ID etc...
            errorType = ErrorType.ASSIGNMENT_TO_LIST_LABEL;
        }
        errMgr.grammarError(errorType, g.fileName, x, x.getText(), expr);
    }
    new AttributeChecks(g, r, alt, node, rhs).examineAction();
}

Example 2 with SetAttr

    ANTLRStringStream in = new ANTLRStringStream(actionAST.token.getText());
    in.setLine(actionAST.token.getLine());
    in.setCharPositionInLine(actionAST.token.getCharPositionInLine());

        }
    };
    ActionSplitter splitter = new ActionSplitter(in, listener);
    // forces eval, triggers listener methods
    splitter.getActionTokens();
    return dependent[0];
}

Example 3 with SetAttr

use of org.antlr.v4.codegen.model.chunk.SetAttr in project antlr4 by antlr.
