QueueElementIF, QuickSerializable

public abstract class TapestryPrefixRouteMsg

extends Object

implements QueueElementIF, QuickSerializable

Messages sent from one OceanStore machine to some other, hopefully with a node GUID that closely matches the given one. The desired GUID to be matched is placed in peer when ! inbound. Because the recipient of this message is unknown to the sender, it cannot be MAC'ed.

Implementation-wise, this is simply a route-to-root operation which is received by the node closest to the (likely non-existent) root. If the root exists, it is equivalent to a TapestryRouteMsg with mac == false.
