Re: [henshin-dev] programatically creating rules and Graphs

[Christian Krause <henshin.ck@xxxxxxxxx>]

Hi.

that is very easy. You can use the HenshinFactory to create rules etc. at runtime. It would look like this:

Rule rule = HenshinFactory.eINSTANCE.createRule();
...

After you have created your rules or units, you can directly apply them using the interpreter (see the interpreter wiki and the source code in the examples).

Another way to create a rule (or transformation unit etc.) is using higher-order (HO) transformations. Here the idea is to create or modify a rule or unit using a transformation. We currently have two examples of HO-transformations on our website. This one here is good starting point:

http://www.eclipse.org/modeling/emft/henshin/examples.php?example=combpattern

There a rule which matches a comb-like pattern of variable width is created using a HO-order transformation (see section "Generating and matching the comb pattern").

I hope this helps.

Cheers,
Christian

hi all,
I want to programatically create a Rule in a transformation system. I want to create rules programatically and then programatically combine their left and right hand side. Is there a way to create Graph, Rule programatically?

Best
