Code Generation - Interaction Diagrams

During code generation from Interaction (Sequence) diagrams in a Class, Enterprise Architect applies its system engineering graph optimizer to transform the Class constructs into programmatic paradigms. Messages and Fragments are identified as two of the several action types based on their functionality, and Enterprise Architect uses the code generation templates to render their behavior accordingly.

Call Message Properties


  • To be able to generate code from behavioral models, all behavioral constructs should be contained within a Class
  • For an Interaction (Sequence) diagram, the behavioral code generation engine expects the Sequence diagram and all its associated messages and interaction fragments to be encapsulated within an interaction element
