Participants

• AbstractClass (Application)

• defines abstract primitive operations that concrete subclasses define to implement steps of an algorithm.
• implements a template method defining the skeleton of an algorithm. The template method calls primitive operations as well as operations defined in AbstractClass or those of other objects.
• ConcreteClass (MyApplication)

• implements the primitive operations to carry out subclass-specific steps of the algorithm.
