28.5 java.net.DatagramPacket (JDK 1.0)

This class implements a "packet" of data that may be sent or received over the network through a DatagramSocket. One of the DatagramPacket constructors specifies an array of binary data to be sent with its destination address and port. A packet created with this constructor may then be sent with the send() method of a DatagramSocket. The other DatagramPacket constructor specifies an array of bytes into which data should be received. The receive() method of DatagramSocket waits for data and stores it in a DatagramPacket created in this way. The contents and sender of a received packet may be queried with the DatagramPacket instance methods.

public final class DatagramPacket extends Object {
    // Public Constructors
            public DatagramPacket(byte[] ibuf, int ilength);
            public DatagramPacket(byte[] ibuf, int ilength, InetAddress iaddr, int iport);
    // Public Instance Methods
            public synchronized InetAddress getAddress();
            public synchronized byte[] getData();
            public synchronized int getLength();
            public synchronized int getPort();
