Class MasterTransfer

java.lang.Object

com.sleepycat.je.rep.impl.node.MasterTransfer

public class MasterTransfer
extends Object

A Master Transfer operation.

Each Master Transfer operation uses a separate instance of this class. There is usually no more than one instance in the lifetime of a master node, because if the transfer succeeds, the old master node environment becomes invalid and must be closed. However, if an operation times out, another operation can try again later. Or, a second operation can "forcibly" supersede an existing operation in progress.
