Class ReadOnlyRequestProcessor

java.lang.Object
  extended by java.lang.Thread
      extended by org.apache.zookeeper.server.quorum.ReadOnlyRequestProcessor
All Implemented Interfaces:
Runnable, RequestProcessor

public class ReadOnlyRequestProcessor
extends Thread
implements RequestProcessor

This processor is at the beginning of the ReadOnlyZooKeeperServer's processors chain. All it does is, it passes read-only operations (e.g. OpCode.getData, OpCode.exists) through to the next processor, but drops state-changing operations (e.g. OpCode.create, OpCode.setData).
