Interface DGC
public
interface
DGC
extends Remote
The DGC implementation is used for the server side during the distributed
garbage collection. This interface contains the two methods: dirty and clean.
A dirty call is made when a remote reference is unmarshaled in a client. A
corresponding clean call is made by client it no longer uses that remote
reference. A reference to a remote object is also automatically released
after so called lease period that starts after the dirty call is received. It
is the client's responsibility to renew the leases, by making additional
dirty calls before such leases expire.
| Method Summary |
|---|
| void | clean(ObjID[] ids, long sequenceNum, VMID vmid, boolean strong)
Mark the given objects as no longer used on the client side.
|
| Lease | dirty(ObjID[] ids, long sequenceNum, Lease lease)
Mark the given objects referecnes as used on the client side.

public void clean(
ObjID[] ids, long sequenceNum,
VMID vmid, boolean strong)
Mark the given objects as no longer used on the client side.
Parameters: ids the ids of the objects that are no longer used. sequenceNum the number of the call (used to detect and discard late vmid the VMID of the client. strong make the "strong" clean call ("strong" calls are scheduled
after the failed dirty calls).
Mark the given objects referecnes as used on the client side.
Parameters: ids the ids of the used objects. sequenceNum the number of the call (used to detect and discard late
