All Implemented Interfaces:

Comparable, QuickSerializable

public class PublishInfo

extends Object

implements Comparable, QuickSerializable

PublishInfo.java The class that encapsulates metadata about a particular replica of an object. The primary info of note is the GUID of its current location, but PublishInfo also keeps track of the distance to this replica, the lasthop taken to get here, and the level of the next hop on the publication path.

Constructor Detail

PublishInfo

public PublishInfo(SecureHash src,
                   DDTag tag,
                   NodeId lasthop)

The routing level that we exit this node at, on the publication path. Using an index starting with 0. If this node is the root, the value is set to -1.
