org.eclipse.php.internal.core.phar.digest.Digest
org.jgroups.protocols.pbcast.Digest
A message digest, which is used by the PBCAST layer for gossiping (also used by NAKACK for keeping track of current seqnos for all members). It contains pairs of senders and a range of seqnos (low and high), where each sender is associated with its highest and lowest seqnos seen so far. That is, the lowest seqno which was not yet garbage-collected and the highest that was seen so far and is deliverable (or was already delivered) to the application. A range of [0 - 0] means no messages have been received yet.
April 3 2001 (bela): Added high_seqnos_seen member. It is used to disseminate information about the last (highest) message M received from a sender P. Since we might be using a negative acknowledgment message numbering scheme, we would never know if the last message was lost. Therefore we periodically gossip and include the last message seqno. Members who haven't seen it (e.g. because msg was dropped) will request a retransmission. See DESIGN for details. @author Bela Ban

org.restlet.data.Digest
Describes a digest value and the digest algorithm used. Digests can have several use cases such as ensuring the integrity of representations exchanges between resources, or for authentication purpose. @see Representation#getDigest() @author Jerome Louvel
