Populating communication diagrams

You can create and populate communication diagrams with elements to understand the interactions between the objects in the context of a classifier, such as collaborations or classes. You can add lifelines that represent the objects, such as collaboration roles, and message pathways and messages to represent the flow of information between the objects in the interaction.
  • Creating lifelines in UML diagrams
    In UML diagrams, such as sequence and communication diagrams, you can create lifelines to represent objects in a system.
  • Creating message pathways in communication diagrams
    To show the messages that pass between the lifelines in a communication diagram, you must begin by creating a message pathway.
  • Creating messages in communication diagrams
    In communication diagrams, you can create messages to represent the communication that occurs between participants in interactions. You can add, delete, reposition, and assign new signatures to messages in an interaction frame.
  • Showing message signatures
    In sequence diagrams and communication diagrams, you can show operation signatures or message signatures of individual messages to visually represent communication in interactions.
