Examples of org.antlr.v4.runtime.tree.ParseTree

org.antlr.v4.runtime.tree.ParseTree
An interface to access the tree of {@link RuleContext} objects createdduring a parse that makes the data structure look like a simple parse tree. This node represents both internal nodes, rule invocations, and leaf nodes, token matches.
The payload is either a {@link Token} or a {@link RuleContext} object.

        String code = "a = 2 / 1 * 2 + 2";
        String expected = "2 2 1 2 DIV MUL ADD 0 MSTORE";


    SerpentParser parser = ParserUtils.getParser(SerpentLexer.class,
        SerpentParser.class, code);
        ParseTree tree = parser.parse();


        String result = new SerpentToAssemblyCompiler().visit(tree);
        result = result.replaceAll("\\s+", " ");
        result = result.trim();
