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.

  • Constructor Summary

    Constructors 
    Constructor Description
    PeerID​(byte[] id, Destination address)  
    PeerID​(byte[] dest_hash, I2PSnarkUtil util)
    Creates a PeerID from a destHash
    PeerID​(Map<String,​BEValue> m)
    Creates a PeerID from a Map containing BEncoded peer id, ip and port.
    PeerID​(BDecoder be)
    Creates a PeerID from a BDecoder.

  • Method Summary

    Modifier and Type Method Description
    int compareTo​(PeerID pid)
    Deprecated.
    unused? and will NPE now that address can be null?
    boolean equals​(Object o)
    Two PeerIDs are equal when they have the same dest hash
    Destination getAddress()
    Get the destination.
    byte[] getDestHash()  
    byte[] getID()  
    int getPort()  
    int hashCode()
    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 sameID​(PeerID pid)
    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
    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.

    • getID

      public byte[] getID()

    • setID

      public void setID​(byte[] xid)
      for connecting out to peer based on desthash @since 0.8.1

    • 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.
      Returns:
      Dest or null if unknown

    • getPort

      public int getPort()

    • getDestHash

      public byte[] getDestHash()
      Since:
      0.8.1

    • hashCode

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

    • sameID

      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:
      equals in class Object

    • compareTo

      @Deprecated public int compareTo​(PeerID pid)
      Deprecated.
      unused? and will NPE now that address can be null?
      Compares port, address and id.
      Specified by:
      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.
