Programmatical creation [message #1759430]

Hi,

In order to modify OCL ASTs I would like to create an OperationCallExp to replace one I don't like (with(in) reason). I want to instantiate an "oclIsTypeOF" operation.
Creating the OperationCallExp object is made easy thanks the EcoreFactory, and modifying its fields is straight forward using Ecore eSetters. Plugin a source, changing operation code is ok.

Troubles to perform the creation happen when I try to instantiate an EOperation to fill the referredOperation field. I've tried many ways, investigated in the Ecore code and documentation, but I can't make it.

Do you have any hint where to look for in the documentation and/or code and/or test code to instantiate such EOperation from scratch (I mean, no parsing) ?

Thank you,
Edouard

See your reply on the start/end thread.

Programmatically, IIRC there is an additionalOperations capability to register alien operations. Search the JUnit tests for an example. I never understood them, but did realize that they could not be serialized to XMI. Hence the Pivot OCL uses true models that can have true XMI references.
