## Package java.rmi.dgc Description

Provides classes and interface for RMI distributed garbage-collection (DGC). When the RMI server returns an object to its client (caller of the remote method), it tracks the remote object's usage in the client. When there are no more references to the remote object on the client, or if the reference's ``lease'' expires and not renewed, the server garbage-collects the remote object.

Since:
  JDK1.1
