Examples of GrammarTransformPipeline

    // update grammar AST and set rule's AST.
    RULES.setChild(prevRuleAST.getChildIndex(), t);
    r.ast = t;


    // Reduce sets in newly created rule tree
    GrammarTransformPipeline transform = new GrammarTransformPipeline(g, g.tool);
    transform.reduceBlocksToSets(r.ast);
    transform.expandParameterizedLoops(r.ast);


    // Rerun semantic checks on the new rule
    RuleCollector ruleCollector = new RuleCollector(g);
    ruleCollector.visit(t, "rule");
    BasicSemanticChecks basics = new BasicSemanticChecks(g, ruleCollector);

Examples of org.antlr.v4.tool.GrammarTransformPipeline
