      • getObjectName

        public java.lang.String getObjectName​(java.lang.Object obj)
        Description copied from interface: IEmfService
        Returns the human readable name of a given object or the EMF id if no name can be found. The method tries to access a modeled attribute "name" or "id" in this order. If no attribute with this name is modeled, the first attribute whose value is a String or TranslatableTextFragment is returned, otherwise null .
        Specified by:
        getObjectName in interface IEmfService
        Parameters:
        obj - the object to get a name for
        Returns:
        the value of attribute "name" or the EMF id if no attribute "name" exists

      • getEObject

        public org.eclipse.emf.ecore.EObject getEObject​(java.lang.Object object)
        Description copied from interface: IEmfService
        Tries to convert the given object to a EObject
        • using #adaptObject(Object, Class),
        • unwrapping an IStructuredSelection.
        Specified by:
        getEObject in interface IEmfService
        Parameters:
        object - the object to convert
        Returns:
        the target object or null

      • getFile

        public org.eclipse.core.resources.IFile getFile​(org.eclipse.emf.ecore.EObject object)
        Description copied from interface: IEmfService
        Returns the Eclipse file for the given EObject's Resource . Note that the file is null for objects in
        • archives,
        • closed projects,
        • not yet persisted resources or not yet persisted EObjects in already persisted resources. In this respect this methods behaves asymmetric to the handle-only resource APIs like IProject.getFile(String).
        Specified by:
        getFile in interface IEmfService
        Parameters:
        object - the model object to get the file for
        Returns:
        the partition file or null under the mentioned circumstances
        See Also:
        IEmfService.getFile(URI)

      • getFile

        Description copied from interface: IEmfService
        Returns the Eclipse file for the given URI. Note that the file is null for objects in
        • archives,
        • closed projects,
        • not yet persisted resources or not yet persisted EObjects in already persisted resources. In this respect this methods behaves asymmetric to the handle-only resource APIs like IProject.getFile(String).
        Specified by:
