public interface ResourceServer

The resource server interface is implemented by objects which manage low level scarce resources and inform applications of changes in their status which may have happened due to factors beyond the control of the application. Any application wishing to use a resource controlled by an object implementing the ResourceServer interface must request access to that resource via an object implementing the ResourceProxy interface, and should release the resource via the same object when exclusive access to the resource is no longer needed.
