About the Action Language Helper (ALH) API

fas fa-book

Many tasks that can't be achieved using just basic SysML or the scripting languages available as action languages for MagicDraw® UML, MagicDraw SysML Plugin, Magic Cyber-Systems Engineer ® (Cameo Systems Modeler®), and Magic Model Analyst® (Cameo Simulation Toolkit®) can be achieved together with the vendor-specific Action Language Helper (ALH) API. The ALH API operations are recognised from most supported scripting languages, and can be invoked by prefixing commands with ALH..

For an example of using ALH visit:

The vendor-specific Action Language Helper (ALH) API can be accessed from all of the various action scripting languages available in MagicDraw, Cameo Systems Modeler, and Cameo Simulation Toolkit
Cameo Simulation Toolkit handles OpaqueExpression and OpaqueBehavior including these action scripting languages: English (built-in), Alf (via plugin), BeanShell, JavaScript, JavaScript Rhino, Groovy, ...
Consider also the UML-closer Action Language for Foundational UML (Alf) (requires an additional commercial plugin).
