Returns the IP address of the machine to which this datagram is being sent or from which the datagram was received.
o getData()
Returns the data received or the data to be sent.
o getLength()
Returns the length of the data to be sent or the length of the data received.
o getNewDatagramPacket()
returns an initialized instance of a UnsynchDatagramPacket
o getPort()
Returns the port number on the remote host to which this datagram is being sent or from which the datagram was received.
o reinitialize()
re-initializes the packet for reuse idea taken from Singhal etal paper from IBM TJ Watson Research Center

Constructors

o UnsynchDatagramPacket 
 public UnsynchDatagramPacket(byte ibuf[],
                              int ilength,
                              InetAddress iaddr,
                              int iport)
Constructs a datagram packet for sending packets of length ilength to the specified port number on the specified host. The length argument must be less than or equal to ibuf.length.

Parameters:
ibuf - the packet data.
ilength - the packet length.
iaddr - the destination address.
iport - the destination port number.
