State-Machines and Code Generation

Generating Code from State-Machine Diagrams
We introduce the ability to generate code from state-machine diagrams in version 0.2.3 of the code generation feature plug-in. Code is generated from the diagram itself, and no additional mark-up of the model is required; that is, nothing over and above the usual mark-up required for Tasking Event-B, such as identifying non-typing/typing invariants, and guards etc. State-machine(s) are created in a machine using the existing state-machine plug-in, subject to the limitations described below.
Limitations/What Can Be Translated
The current code generation tool is restricted to generating code for a single Event-B machine containing one or more state-machines. We have yet to explore the decomposition/composition of machines containing state-machines.
We do not handle nested state-machines.
