Constructors

new IntegerRenderer() #

Creates a new Object instance.

Object instances have no meaningful state, and are only useful through their identity. An Object instance is equal to itself only.

IntegerRenderer();

factory IntegerRenderer.instance() #

Returns the instance.

factory IntegerRenderer.instance() {
 if (_INSTANCE == null) {
   _INSTANCE = new IntegerRenderer();
