[ecf-dev] How to register a custom RegistrySharedObject Implementation
|
Hi all,
for custom error handling (see older discussion on this list) we
register a custom RegistrySharedObject implementation by overriding
protected IRemoteServiceContainer createRSContainer(
@SuppressWarnings("rawtypes") final ServiceReference
serviceReference, final Map<String, Object> properties,
final ContainerTypeDescription containerTypeDescription)
in a custom IHostContainerSelector. After upgrading to the latest ECF
release we recognized that this method is not called anymore, but the
one with the added "String[] intents" argument. The implementation there
seem to be very different from before so we currently don't know where
to register our custom RegistrySharedObject.
Our code before (shortened):
final ID adapterID =
IDFactory.getDefault().createStringID(IRemoteServiceContainerAdapter.class.getName());
final ISharedObjectManager manager = container.getSharedObjectManager();
ISharedObject so = manager.getSharedObject(adapterID);
if (so == null) {
so = new P4RegistrySharedObject(); // <- Custom RegistrySharedObject
manager.addSharedObject(adapterID, so, null);
}
return new RemoteServiceContainer(container,
(IRemoteServiceContainerAdapter) so);
In the current implementation this code seems to be moved - somewhere in
the area of AbstractHostContainerSelector.
I tried to suppy our RegistrySharedObject as argument for adapter to
return new RemoteServiceContainer(container, adapter);
but that does not seems to work as expected.
As shown the the below StackTrace below the instance of the
RegistrySharedObject in the end is provided by
RemoteServiceContainerAdapterFactory which is registered in
org.eclipse.ecf.internal.provider.remoteservice.Activator
as an adapter of the an IAdapterManager.
Registering an alternative Factory in the AdapterManager will probably
not work, since i think i read that the first one will be returned in
case there are multiple Adapters for the same id ... ?
Any hints on what is the best or expected way of registering our own
Object are very welcome!
Thanks!
Bye Peter
