UML 2 Activity and Action Models, Part 6: Structured Activities



Conrad E. Bock


This is the sixth in a series introducing the activity model in the Unified Modeling Language, version 2 (UML 2), and how it integrates with the action model [1]. The first article gives an overview of activities and actions [2], while the next four cover models of the kind typically used for graphical flow languages. This one describes models for languages that usually have textual presentations. It covers the structured nodes for sequencing, conditionals, loops, and expansion regions for operating on collections, as well as exception handlers, variables, and action pins.
