MODE_UPDATE_AFTER_RW

If this constant is used as an argument of the constructor, the new state is reported to the snooper after the Read-Write-Access is over.

MODE_UPDATE_DURING_RW

If this constant is used as an argument of the constructor, every state change during a Read-Write-Access is reported to the snooper.

PassiveReplication()

Construct a PassiveReplication object.

PassiveReplication(int)

Construct a PassiveReplication object.

 public static final int MODE_UPDATE_DURING_RW

If this constant is used as an argument of the constructor, every state change during a Read-Write-Access is reported to the snooper. (If this object is used for locking purpose, this is not always true. For details please read the API User's Guide.)

 public static final int MODE_UPDATE_AFTER_RW

If this constant is used as an argument of the constructor, the new state is reported to the snooper after the Read-Write-Access is over. Read-Write-Access is over if there is either global Read-Access or an other cite gets Read-Write-Access.

 public PassiveReplication()

Construct a PassiveReplication object. The update mode is MODE_UPDATE_AFTER_RW.

 public PassiveReplication(int mode)

Construct a PassiveReplication object.

Parameters:

mode - The update mode
