Examples of org.locationtech.udig.catalog.IService.canResolve()

org.locationtech.udig.catalog.IService.canResolve()
Harded coded to capture the IService contract.
That is we *must* resolve the following:
- IService: this
- IServiceInfo.class: getInfo
- List.class: members
- ICatalog.class: parent
Here is an implementation example (for something that can adapt to DataStore):
```
  public <T> boolean canResolve( Class<T> adaptee ) { return adaptee != null && (adaptee.isAssignableFrom(DataStore.class) || super.canResolve(adaptee)); }  
```

            for( ILayer layer : layers ) {


                IService service = null;
                try {
                    service = layer.getGeoResource().service(null);
                    if (service.canResolve(ServiceMover.class)) {
                        ServiceMover tmp = service.resolve(ServiceMover.class, null);
                        String msg = tmp.move(projectDataFolder);
                        if (msg != null) {


                            MessageDialog.openError(PlatformUI.getWorkbench().getDisplay()
