Creating a part decomposition

Use the product to decompose an instance line on a sequence diagram into a series of parts.

About this task

For example, if you have a composite class view in one sequence diagram and want to navigate to its parts, you can click the composite class and open a collaboration, which shows how its internal parts communicate for a particular scenario.

Part decomposition is a specialization of an interaction occurrence.

Procedure

  1. Open the Features window for the instance line. The Classifier Role window opens.
  2. Specify the reference sequence diagram using the Decomposed list.
  3. Click OK.

Results

In the sequence diagram, the name of the reference sequence diagram is added to the classifier role label (after the word "ref"), as shown in this example.

name of the reference sequence diagram is added to the classifier role label (after the word "ref")

As with other interaction occurrences, navigate to the reference sequence diagram by right-clicking the instance line and selecting Open Reference Sequence Diagram.
