Hi, Yury,
In the development of UML support in the OCL parser:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=163808
I will be adding API to the EvaluationEnvironment interface to support,
among other things, custom evaluation of property and association-class
navigation. The EvaluationEnvironment will also be more involved in the
evaluation of operations.
These changes should give you the hooks that you need to access intermediate
values, as ultimately all computations in OCL are either operation calls or
property/association-class navigation and these values will always be
provided by the EvaluationEnvironment. Please add yourself to the cc list
of this bug and add a comment to ensure that your requirements will be
considered. The intent is to make it easy for clients to extend the
interpreter via the EvaluationEnvironment, without exposing the core
evaluation engine.
Cheers,
Christian
