Examples of ParseTreeMatch

org.antlr.v4.runtime.tree.pattern.ParseTreeMatch
Represents the result of matching a {@link ParseTree} against a tree pattern.

Examples of org.antlr.v4.runtime.tree.pattern.ParseTreeMatch

      "ID : [a-z]+ ;\n" +
      "WS : [ \\r\\n\\t]+ -> skip ;\n";


    String input = "x ;";
    String pattern = "<id:ID>;";
    ParseTreeMatch m = checkPatternMatch(grammar, "s", input, pattern, "X8");
    assertEquals("{ID=[x], id=[x]}", m.getLabels().toString());
    assertNotNull(m.get("id"));
    assertNotNull(m.get("ID"));
    assertEquals("x", m.get("id").getText());
    assertEquals("x", m.get("ID").getText());
    assertEquals("[x]", m.getAll("id").toString());
    assertEquals("[x]", m.getAll("ID").toString());


    assertNull(m.get("undefined"));
    assertEquals("[]", m.getAll("undefined").toString());
