Some questions about Class.javajet template [message #530783]

Am I understand correct, that Class.javajet template is used in default case by EMF twice: to produce interface and to produce implementation?

Is it possible (should be) to see it all in debugger. Can you give an advice how to run codegen in debugger with ability to set breakpoints in EMF code (which is used from multiple plugins)? I can see code, adding sources, but don't see how to start it all in debugger, except of probably going with org.eclipse.emf.codegen.ecore.Generator from command line... But then breakpoints is a pain, no IDE to help.

Thanks

Alexey

Try setting a breakpoint in AbstractGeneratorAdapter.generateJava.

Ed, thanks for answering. Please let me ask for some clarification:

So am I understand correct, that to debug emf code generation the only way is:
1. set up eclipse to listen to remote java application (with localhost as a server)
2. set breakpoints in emf java source
3. start org.eclipse.emf.codegen.ecore.Generator from command line in debugging mode

And there is no (easy) way to have emf code generation running from withing eclipse in debugging mode. Normally you would run codegen pluging from UI, selecting e.g. Generate Model. But no way to set it up to run it in debug mode?

Alexey,

You can launch a runtime workbench under debug control to
debug/monitor/observe any parts of the IDE itself.
