====Leased Object References==== ====Leased Object References====
-A leased object reference is a remote far reference that grants access to a remote object for a limited period of time. When the time period has elapsed, the access to the remote object is terminated and the leased reference is said to //expire//. Similarly to remote far references, a leased reference abstracts client objects from the actual network connection state. Client objects can send a message to the remote object even if a leased references is disconnected at that time. Message are accumulated in order to be transmitted when the reference becomes reconnected. When the leased reference expires it, messages are discarded since an expired leased reference behaves as a //permanently// disconnected remote far reference. The figure below shows a diagram of the different states of a leased reference.+A leased object reference is a remote far reference that grants access to a remote object for a limited period of time.
