Example 1 with QRetValueRef

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

the class ActionTranslator method qualifiedAttr.

@Override
public void qualifiedAttr(String expr, Token x, Token y) {
    gen.g.tool.log("action-translator", "qattr " + x + "." + y);
    if (node.resolver.resolveToAttribute(x.getText(), node) != null) {
        // must be a member access to a predefined attribute like $ctx.foo
        attr(expr, x);
        chunks.add(new ActionText(nodeContext, "." + y.getText()));
        return;
    }
    Attribute a = node.resolver.resolveToAttribute(x.getText(), y.getText(), node);
    if (a == null) {

        gen.g.tool.errMgr.grammarError(ErrorType.UNKNOWN_SIMPLE_ATTRIBUTE, gen.g.fileName, x, x.getText(), "rule");
        return;
