Examples of org.antlr.runtime.tree.TreeWizard$TreePattern

org.antlr.runtime.tree.TreeWizard
When using %label:TOKENNAME in a tree for parse(), we must track the label.

    boolean valid = wiz.parse(t, "(A . .)");
    assertTrue(valid);
  }


  @Test public void testParseWithText() throws Exception {
    TreeWizard wiz = new TreeWizard(adaptor, tokens);
    CommonTree t = (CommonTree)wiz.create("(A B[foo] C[bar])");
    // C pattern has no text arg so despite [bar] in t, no need
    // to match text--check structure only.
    boolean valid = wiz.parse(t, "(A B[foo] C)");
    assertTrue(valid);
