In the above [[Unified Modeling Language|UML]] [[class diagram]], the <code>AbstractClass</code> defines a <code>templateMethod()</code> operation that defines the skeleton (template) of a behavior by
* implementing the invariant parts of the behavior and
* sending to '''self''' the messages  <code>primitive1()</code> and <code>primitive2()</code> , which, because they are implemented in <code>SubClass1</code> , allow that subclass to provide a variant implementation of those parts of the algorithm.
