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

All Methods Static Methods Instance Methods Concrete Methods Deprecated Methods
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.

    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.
