RootContainer
- the type of root containers in which model elements may reside (e.g. aResource
)ModelObject
- the type representing a model element; can be simply anEObject
or a surrogate key

public interface IEcoreReadOperations<RootContainer,ModelObject>
Interface for commands that read some representation of an instance of an Ecore metamodel.IModelReadOperations
is provided as the default case where the instance model is simply an EMF model.Note that not all representations may support / preserve ordered collections.
- Since:
- 2.1
- No Extend:
- This interface is not intended to be implemented by clients.
