EAL (Executable Action Language) Documentation[edit source]

Welcome to the Executable Action Language (EAL) section of the MDriven Documentation. EAL extends OCL with imperative features so you can perform actions: assign values, create/delete objects, mutate collections, save to persistence, navigate ViewModels, call external APIs, and transform data.

If you already know OCL for expressions and constraints, EAL lets you do things with those results.

Introduction to EAL[edit source]

Start with the core ideas and where EAL is used (buttons/actions, state machines, ViewModels, ServerSide ViewModels).

Writing EAL Actions[edit source]

Learn the building blocks you’ll use in actions.

Assignment & sequencing: :=, ;
Conditionals & loops: whentrue, whenfalse, foreach
Object lifecycle: create, delete, setToNull
Persistence: Save, Refresh, Search, ReQuery
