Visually developing behavioral features of applications

You can use sequence diagrams to create a graphical representation of the source elements in a system or application to understand and develop behaviors and interactions between classes and data types.

You can create new sequence diagrams, populate existing sequence diagrams with source elements, and add lifelines, messages, and combined fragments to sequence diagrams.

Creating and populating sequence diagrams
You can create and populate sequence diagrams with source elements to understand and develop behaviors and interactions between classes and interfaces or between classes and data types in applications.
Managing lifelines in sequence diagrams
In sequence diagrams, you can create lifelines to represent properties within your application and specify their types.
Creating and editing messages on lifelines in sequence diagrams
In sequence diagrams, you can create and edit messages between lifelines.
Adding execution specifications to interactions in sequence diagrams
In sequence diagrams, you can add execution specifications to lifelines to show the start and finish behaviors or flow of interactions to visually represent interactions in applications. Execution specifications represent the execution of behaviors.
Managing combined fragments in sequence diagrams
In sequence diagrams, you can add combined fragments to lifelines to represent constructs, such as options, alternatives, and loops, for visual representation of applications.
Referencing interactions from within other interactions in sequence diagrams
In sequence diagrams, you can reference an interaction from the body of another interaction for the purpose of visual representation. This reference is called an interaction use. You can then reuse the definitions in an interaction to abstract and simplify your application.
