Class RemoteCacheRequestMessage

java.lang.Object
  |
  +--ostore.dtree.RemoteCacheRequestMessage

All Implemented Interfaces:

QueueElementIF, QuickSerializable

public class RemoteCacheRequestMessage

extends Object

implements QueueElementIF, QuickSerializable

The RemoteCacheRequestMessage is a message sent by the cache to request a block known only by its vhash. The message is sent via the DTreeNode to the parent node in the dissemination tree. The DTreeNode on the remote machine unpacks the message and dispatches it to the MemoryCache on the remote node. That cache may respond to the request by sending a RemoteCacheReplyMessage back down the dissemination tree or may propagate the request up to its parent in the dissemination tree.
