[henshin-dev] Nested multi-rules in diagram editor

[Christian Krause <henshin.ck@xxxxxxxxx>]

Hi,

I am currently adding support for arbitrary nesting of multi-rules in 
the graphical editor. The parameters of an action determine the nesting 
of the multi-rules. For example the action <<delete*:A,B,C>> means that 
there there is the following nesting structure:

- Rule A:
  - Multi-rule B:
    - Multi-rule C:

and that the element with the action is deleted in the multi-rule C. I 
am trying to apply this to the OO2RDB example which makes heavy use of 
nested multi-rules. You can find a screenshot in the attachment. If you 
have comments or ideas for improvements, pls let me know.

Also, I am integrating the actions into the model, which allows you, 
e.g., to make complex editing operations as supported in the graphical 
editor, also in the tree-based editor. The integration is very 
lightweight: it consists of a single datatype "Action" and an additional 
(volatile) attribute GraphElement.action:Action. That's it.

Cheers,
Christian
