Class CommitProcessor

java.lang.Object

java.lang.Thread

org.apache.zookeeper.server.ZooKeeperThread

org.apache.zookeeper.server.ZooKeeperCriticalThread

org.apache.zookeeper.server.quorum.CommitProcessor

All Implemented Interfaces:

java.lang.Runnable, RequestProcessor

public class CommitProcessor
extends ZooKeeperCriticalThread
implements RequestProcessor

This RequestProcessor matches the incoming committed requests with the locally submitted requests. The trick is that locally submitted requests that change the state of the system will come back as incoming committed requests, so we need to match them up.
