net.jxta.impl.id.binaryID
Class PeerGroupBinaryID

java.lang.Object
  extended by net.jxta.id.ID
      extended by net.jxta.peergroup.PeerGroupID
          extended by net.jxta.impl.id.binaryID.PeerGroupBinaryID
All Implemented Interfaces:
Serializable
public final class PeerGroupBinaryID
extends PeerGroupID

This class implements a PeerGroup ID. Each peer group is assigned a unique peer id.BinaryID id are used to implement peer group id. Because this id is built with BinaryID, pulling the parent group requires a little work. The parent group is the first id, with the second following, seperated by a dash '-' character.

Field Detail

id

protected String id
This is the id string used in the XML of the id. The format is TX0..Xn where T is the type and X0 through Xn are the base64 encoded id.

Constructor Detail

PeerGroupBinaryID

public PeerGroupBinaryID(PeerGroupID parent,
                         byte[] data,
                         boolean lengthIncluded)
Constructor for creating a new PeerGroupID with a unique ID and a parent.

Note that only the ID for the parent is obtained and not the parent and the grandparent.

Parameters:
parent - Parent peer group.
data - data byte array to be used as the id.
lengthIncluded - If true, the first byte in the data array is the length of the remaining bytes.

PeerGroupBinaryID

protected PeerGroupBinaryID(String id)
Creates a ID from a string. Note that the ID is not currently validated.

Parameters:
id - Value of ID.

PeerGroupBinaryID

public PeerGroupBinaryID(byte[] data,
                         boolean lengthIncluded)
Constructor for creating a new PeerGroupID with a unique ID and a parent.

Parameters:
data - DOCUMENT ME!
lengthIncluded - DOCUMENT ME!

PeerGroupBinaryID

public PeerGroupBinaryID()
Constructor for creating a new PeerGroupID. Note that this creates an invalid ID but is required for serialization.

PeerGroupBinaryID

public PeerGroupBinaryID(BinaryID id)
Constructor. Intializes contents from provided ID. This PeerGroupID has no parent.

Parameters:
id - the ID data

Specified by:
getParentPeerGroupID in class PeerGroupID

getID

protected String getID()
returns the coded ID without the binaryid tag.

Returns:
The coded ID without the binaryid tag.
