Using OCL to query; how to integrate in my metamodel [message #808693]

Hi guys,

Hope you guys can understand and help me.

I am building a metamodel in which the main element, called ActiveStructureAssigment, has an EReference (which is 1..1 and let´s supposed it´s named 'has') to an Eclass called ActiveStructureElement, which is the main element of another metamodel and is further specialized in other classes.

What I want to do is: when instatiating the metamodel, I want to be able to define the EReference aforementioned using OCL. For example:

has: ActiveStructureElementX.allInstances()->any();

Is there any way to do something like this? I tried to look up for examples or resources but couldnt found.

Any help is appreciated!

Thanks!

Hi

Look at the OCLinEcore Tutorial in the Help Contents->OCL Documentation.
