Emap with EMF (in ecorediagram) [message #687766]

Hi,

I have searched about my problem before writing this topic but I have not found answers to my problem.

First I want to create an attribute with Etype Emap <K,V> : K =EString and V = EFloat but I don't know how apply that in the metamodel (in the diagram. Ecorediagram)

Second I want to create an attribute of type Vector<X> : X reference to a class that I have already defined in my metamodel.

Thankx,
Best Regards,
AménieV

You can look at how Ecore does this for EAnnotation's eDetails feature
of type EMap<EString, EString>.

You'd have to define an EDataType for java.util.Vector and define it to
have a type parameter. Then you could, via the outline view, populate
the generic type's type argument to reference X.

Hey there!

My problem is little bit same as yours but in my case i have a class whose attribute should be a datatype class which is already defined in my metamodel.i.e

Class A
attr1:Class B

Where class A and Class B are part of my metamodel. I tried creating a datatype named B but this does not seem to work.

Do you have any idea about it. I have searched different forums on it but i could only find your post a little bit relevant to the problem i am facing

Thanks in advance

Is B an EClass or an EDataType. If it's the former, you have to create
a reference not an attribute.
