7.1. Object and Attribute Actions
Definition: An action is an individual operation that performs a single task on an element of a model.
When we write object actions, we write the action for an arbitrary object. The target of the action is specified at run time, and is generally held in an object reference variable.
Definition: An object reference is a value that refers to an object.
An object reference is not the object itself.
