Detailed Description

Client owned objects.

Resources represent objects owned by a Client Object. They are the result of binding to a global resource or by calling API that creates client owned objects.

The client usually has a proxy object associated with the resource that it can use to communicate with the resource. See Proxy.

Resources are destroyed when the client or the bound object is destroyed.
