Java Remote Method Invocation

9.2 The Lease Class

A lease contains a unique virtual machine identifier and a lease duration. A Lease object is used to request and grant leases to remote object references.

package java.rmi.dgc;

public final class Lease implements java.io.Serializable {

	public Lease(VMID id, long duration);

	public VMID getVMID();

	public long getValue();
}

The Lease constructor creates a lease with a specific VMID and lease duration. The VMID may be null.
The getVMID method returns the client VMID associated with the lease.
The getValue method returns the lease duration.
