Chapter 5 Building Dynamic Diagrams
An interaction reference is used to represent one sequence diagram in the body of another. This feature allows you to modularize and reuse commonly-used interactions across a range of sequence diagrams.
An interaction reference can be created in the following diagrams:
In the example below, the user must log in before passing a request to the account page of a website. As the log in process will form a part of many interactions with the site, it has been abstracted to another sequence diagram called "Log In", and is represented here by an interaction reference.
