      private void addForStatement(String name, Type type, Expression init, Expression test, Expression post, BlockBuilder block)
      Append a three-part 'for' statement with an associated variable. This assumes the first part is a local variable declaration with an initializer expression, while the other two parts are just expressions.
      Parameters:

      type - variable type
      init - variable initialization expression
      test - loop test expression (second part of 'for')

      block - statement body block

    • addIndexedForStatement

      public void addIndexedForStatement(String name, String array, BlockBuilder block)
