Method Detail

close

public void close()
           throws java.io.IOException

Description copied from interface: DatagramSocket

Closes the connection.

Specified by:

close in interface DatagramSocket

Throws:

java.io.IOException

receive

public Datagram receive()
                 throws java.io.IOException

Description copied from interface: DatagramSocket

Receives a datagram. When this method returns, the internal buffer in the Datagram object is filled with the data received, starting at the location determined by the offset state variable. The data is ready to be read using the methods of the DataInput interface. This method remains idle until a datagram is received. The internal length state variable in the Datagram object contains the length of the received datagram. If the received data is longer than the length of the internal buffer minus offset, the data is truncated. This method does not change the internal read/write state variable of the Datagram object. Use method Datagram.reset to change the pointer before reading if necessary.

Specified by:

receive in interface DatagramSocket

Returns:

A datagram.

Throws:

java.io.IOException

send

public void send(Datagram datagram)
          throws java.io.IOException

Description copied from interface: DatagramSocket

Sends a datagram. The Datagram object includes the information indicating what data to send, its length, and the address of the receiver. The method sends length bytes starting at the current offset of the Datagram object, where length and offset are internal state variables of the Datagram object.

Specified by:

send in interface DatagramSocket

Parameters:

datagram - A datagram.

Throws:

java.io.IOException

release

public void release(Datagram datagram)

Description copied from interface: DatagramSocket

Returns datagram to this socket for reusability.

Specified by:

release in interface DatagramSocket

Parameters:

datagram - the datagram, which can be reused by this socket

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getSocketAddress

public IPAddress getSocketAddress()

Description copied from interface: DatagramSocket

Returns the address this socket is bound to.

Specified by:

getSocketAddress in interface DatagramSocket

Returns:

the address.

getSocketPort

public int getSocketPort()

Description copied from interface: DatagramSocket

Returns the port this socket is bound to.

Specified by:

getSocketPort in interface DatagramSocket

Returns:

the port.

getIface

public NetworkInterface getIface()

Description copied from interface: DatagramSocket

Returns the interface.

Specified by:

getIface in interface DatagramSocket

Returns:

the interface.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object
