Class PeerID

java.lang.Object
org.klomp.snark.PeerID
All Implemented Interfaces:
Comparable<PeerID>

public class PeerID extends Object implements Comparable<PeerID>
Store the address information about a peer. Prior to 0.8.1, an instantiation required a peer ID, and full Destination address. Starting with 0.8.1, to support compact tracker responses, a PeerID can be instantiated with a Destination Hash alone. The full destination lookup is deferred until getAddress() is called, and the PeerID is not required. Equality is now determined solely by the dest hash.

    Description
    PeerID(byte[] id, Destination address)
     
    PeerID(byte[] dest_hash, I2PSnarkUtil util)

    Description
    int
    Deprecated.
    unused? and will NPE now that address can be null?
    boolean
    Two PeerIDs are equal when they have the same dest hash
    Get the destination.

    int
    The hash code of a PeerID is the hashcode of the desthash
    static String
    idencode(byte[] bs)
    Encode an id as a hex encoded string and remove leading zeros.
    boolean
    Returns true if and only if this peerID and the given peerID have the same destination hash
    void
    setID(byte[] xid)
    for connecting out to peer based on desthash @since 0.8.1
    Returns the String "id@address" where id is the first 4 chars of the base64 encoded id and address is the first 6 chars of the base64 dest (was the base64 hash of the dest) which should match what the bytemonsoon tracker reports on its web pages.

    • getAddress

      public Destination getAddress()
      Get the destination. If this PeerId was instantiated with a destHash, and we have not yet done so, lookup the full destination, which may take up to 10 seconds.

    • hashCode

      public int hashCode()
      The hash code of a PeerID is the hashcode of the desthash
      Overrides:

      public boolean sameID(PeerID pid)
      Returns true if and only if this peerID and the given peerID have the same destination hash
    • equals

      public boolean equals(Object o)
      Two PeerIDs are equal when they have the same dest hash
      Overrides:

    • compareTo

      @Deprecated public int compareTo(PeerID pid)
      Deprecated.

      compareTo in interface Comparable<PeerID>
    • toString

      public String toString()
      Returns the String "id@address" where id is the first 4 chars of the base64 encoded id and address is the first 6 chars of the base64 dest (was the base64 hash of the dest) which should match what the bytemonsoon tracker reports on its web pages.
      Overrides:
      toString in class Object
    • idencode

      public static String idencode(byte[] bs)
      Encode an id as a hex encoded string and remove leading zeros.
