Detailed Description

This class represents a datagram packet which contains data either to be sent or received through a

DatagramSocket

. It holds additional information such as its source or destination host.

Constructor & Destructor Documentation

◆ DatagramPacket() [1/6]

java.net.DatagramPacket.DatagramPacket	(	byte []	data,
		int	length
	)

inline

Constructs a new

DatagramPacket

object to receive data up to

length

bytes.

Parameters

data	a byte array to store the read characters.
length	the length of the data buffer.

◆ DatagramPacket() [2/6]

java.net.DatagramPacket.DatagramPacket	(	byte []	data,
		int	offset,
		int	length
	)

inline

Constructs a new

DatagramPacket

object to receive data up to

length

bytes with a specified buffer offset.

Parameters

data	a byte array to store the read characters.
offset	the offset of the byte array where the bytes is written.
length	the length of the data.

◆ DatagramPacket() [3/6]

java.net.DatagramPacket.DatagramPacket	(	byte []	data,
		int	offset,
		int	length,
		InetAddress	host,
		int	aPort
	)

inline

Constructs a new

DatagramPacket

object to send data to the port

aPort

of the address

host

. The

length

must be lesser than or equal to the size of

data

. The first

length

bytes from the byte array position

offset

are sent.

Parameters

data	a byte array which stores the characters to be sent.
offset	the offset of data where to read from.
length	the length of data.
host	the address of the target host.
aPort	the port of the target host.

◆ DatagramPacket() [4/6]

java.net.DatagramPacket.DatagramPacket	(	byte []	data,
		int	length,
		InetAddress	host,
		int	port
	)

inline

Constructs a new

DatagramPacket

object to send data to the port

aPort

of the address

host

. The

length

must be lesser than or equal to the size of

data

. The first

length

bytes are sent.

Parameters

data	a byte array which stores the characters to be sent.
length	the length of data.
host	the address of the target host.
port	the port of the target host.

◆ DatagramPacket() [5/6]

java.net.DatagramPacket.DatagramPacket	(	byte []	data,
		int	length,
		SocketAddress	sockAddr
	)		throws SocketException

inline

Constructs a new

DatagramPacket

object to send data to the address

sockAddr

. The

length

must be lesser than or equal to the size of

data

. The first

length

bytes of the data are sent.

Parameters

data	the byte array to store the data.
length	the length of the data.
sockAddr	the target host address and port.

Exceptions

SocketException if an error in the underlying protocol occurs.

◆ DatagramPacket() [6/6]

java.net.DatagramPacket.DatagramPacket	(	byte []	data,
		int	offset,
		int	length,
		SocketAddress	sockAddr
	)		throws SocketException

inline

Constructs a new

DatagramPacket

object to send data to the address

sockAddr

. The

length

must be lesser than or equal to the size of

data

. The first

length

bytes of the data are sent.

Parameters

data	the byte array to store the data.
offset	the offset of the data.
length	the length of the data.
sockAddr	the target host address and port.

Exceptions

SocketException if an error in the underlying protocol occurs.

Member Function Documentation

◆ getAddress()

synchronized InetAddress java.net.DatagramPacket.getAddress ( )

inline

Gets the sender or destination IP address of this datagram packet.

Returns: the address from where the datagram was received or to which it is sent.

◆ getData()

synchronized byte [] java.net.DatagramPacket.getData ( )

inline

Gets the data of this datagram packet.

Returns: the received data or the data to be sent.

◆ getLength()

synchronized int java.net.DatagramPacket.getLength ( )

inline

Gets the length of the data stored in this datagram packet.

Returns: the length of the received data or the data to be sent.

◆ getOffset()

synchronized int java.net.DatagramPacket.getOffset ( )

inline

Gets the offset of the data stored in this datagram packet.

Returns: the position of the received data or the data to be sent.

◆ getPort()

synchronized int java.net.DatagramPacket.getPort ( )

inline

Gets the port number of the target or sender host of this datagram packet.

Returns: the port number of the origin or target host.

◆ getSocketAddress()

synchronized SocketAddress java.net.DatagramPacket.getSocketAddress ( )

inline

Gets the host address and the port to which this datagram packet is sent as a

SocketAddress

object.

Returns: the SocketAddress of the target host.

◆ setAddress()

synchronized void java.net.DatagramPacket.setAddress ( InetAddress addr )

inline

Sets the IP address of the target host.

Parameters

addr	the target host address.

◆ setData() [1/2]

synchronized void java.net.DatagramPacket.setData	(	byte []	data,
		int	offset,
		int	byteCount
	)

inline

Sets the data buffer for this datagram packet.

◆ setData() [2/2]

synchronized void java.net.DatagramPacket.setData ( byte [] buf )

inline

Sets the data buffer for this datagram packet. The length of the datagram packet is set to the buffer length.

Parameters
