    when(modelRepository.executeCommand(eq(modeluri), any(CCommand.class))).thenReturn(result);
    modelController.executeCommand(context, modeluri);
    // unload to proxify
    res.unload();
    verify(modelRepository).executeCommand(eq(modeluri), argThat(eEqualTo(setCommand)));
    // No subscribers registered for this incrementalUpdate, therefore no pre-encoded commands are created and the map
    // can remain empty for this test
    verify(sessionController).commandExecuted(eq(modeluri), eq(Suppliers.ofInstance(result)), anySupplier());
}

Example 2 with CCommand

use of org.eclipse.emfcloud.modelserver.command.CCommand in project emfcloud-modelserver by eclipse-emfcloud.

Example 3 with CCommand

use of org.eclipse.emfcloud.modelserver.command.CCommand in project emfcloud-modelserver by eclipse-emfcloud.

the class DefaultModelController method resolveWorkspaceURIs.

/**

 * the complete URIs when referencing EObjects (including the workspace
 * path prefix). With V2 and standalone client, the client no longer has
 * knowledge about the workspace location, and may not be able to provide
 * full URIs. Resolve relative URIs against the current workspace root.
