Chapter 2 Building an Object-Oriented Model

Adding operations to a class

You can add an operation to a class in one of the following two ways:

Add a duplicate operation

Add an operation from a parent class

Adding a duplicate operation to a class

A duplicate operation is an operation that creates and initializes an instance of a class within the class.

When you create a duplicate operation, it has the name Duplicate, which you can modify.

You can define only one duplicate operation to any given class.

ϖTo add a duplicate operation to a class:

1 Double-click a class in the model.

2 Click the Operations tab.

3 Click the Add button.

4 Select Duplicate Operation from the dropdown list.

A duplicate operation, the name Duplicate, is created at the end of the list of operations for the class.
