Hands On with the Alf Action Language: Making Executable Modeling Even Easier

  • Speaker: Ed Seidewitz
  • When: Day 3 : Tuesday May 23rd
  • Do you use the industry-leading model execution capabilities provided by Cameo Simulation Toolkit (CST)? Do you love being able to simulate systems using state machines and activities? But, on the other hand, do you dread the complexity of using activity diagrams to code really detailed behavior? Or do you get annoyed by having limited access your model state if you use a scripting language instead? Now there is a solution! The Alf Plugin gives you the ability to use the OMG-standard Alf action language to write expressions and behaviors in models executed using CST. Alf is a textual language with a familiar Java-like syntax, but it is designed specifically to be used in the context of graphical, executable UML and SysML models. Indeed, behind the scenes, Alf is actually compiled into UML activity models, which are then automatically integrated into your overall model, so they can be seamlessly executed using CST. This tutorial will give you an introduction to the Alf language, instruction on how to install and use the Alf Plugin with CST, and a chance to try it out hands-on. You will be amazed at how much quicker and easier it is to write three lines of Alf code, rather than create by hand an equivalent activity model of 20 or more elements!
