Examples of com.sleepycat.je.rep.impl.node.RepNode

com.sleepycat.je.rep.impl.node.RepNode
Represents a replication node. This class is the locus of operations that manage the state of the node, master, replica, etc. Once the state of a node has been established the thread of control passes over to the Replica or FeederManager instances. Note that both Feeders and the Replica instance may be active in future when we support r2r replication, in addition to m2r replication. For now however, either the FeederManager is active, or the Replica is and the same common thread control can be shared between the two.
