Public Member Functions
int	receive (void *buf, size_t len)
	Receive a data packet from the connected peer host.
bool	isInputReady (timeout_t timeout=TIMEOUT_INF)
	See if input queue has data packets available.
Protected Member Functions
	UDPReceive (const InetAddress &bind, tpport_t port)
	Create a UDP receiver, bind it to a specific interface and port address so that other UDP sockets on remote machines (or the same host) may find and send UDP messages to it, and associate it with a given port on a peer host.
Error	connect (const InetHostAddress &host, tpport_t port)
	Associate this socket with a specified peer host.
bool	isPendingReceive (timeout_t timeout)
	Check for pending data.

	End receiver.

Constructor & Destructor Documentation

UDPReceive::UDPReceive (  const InetAddress &  bind, tpport_t  port )  [protected]

Create a UDP receiver, bind it to a specific interface and port address so that other UDP sockets on remote machines (or the same host) may find and send UDP messages to it, and associate it with a given port on a peer host. On failure to bind, an exception is thrown. Parameters: bind  address to bind this socket to. port  number to bind this socket to.

Member Function Documentation

Error UDPReceive::connect (  const InetHostAddress &  host, tpport_t  port )  [protected]

Associate this socket with a specified peer host. The port number from the constructor will be used. All UDP packets will be sent received from the specified host. Returns: 0 on success, -1 on error. Parameters: host  host network address to connect socket to. port  host transport port to connect socket to. Reimplemented in UDPDuplex.

Error UDPReceive::drop (  const InetMcastAddress &  ia  )  [inline, protected]

Reimplemented from Socket.

void UDPReceive::endReceiver (  void   )  [inline, protected]

End receiver.

SOCKET UDPReceive::getReceiver (  void   )  const [inline, protected]

bool UDPReceive::isInputReady (  timeout_t  timeout = TIMEOUT_INF  )  [inline]

See if input queue has data packets available. Returns: true if data packets available. Parameters: timeout  in milliseconds.

bool UDPReceive::isPendingReceive (  timeout_t  timeout  )  [inline, protected]

Check for pending data. Returns: true if data is waiting. Parameters: timeout  in milliseconds.

Error UDPReceive::join (  const InetMcastAddress &  ia  )  [inline, protected]

Reimplemented from Socket.

int UDPReceive::receive (  void *  buf, size_t  len )  [inline]

Receive a data packet from the connected peer host. Returns: num of bytes actually received. Parameters: buf  address of data receive buffer. len  size of data receive buffer. Reimplemented from UDPSocket.

Error UDPReceive::setMulticast (  bool  enable  )  [inline, protected]

Reimplemented from Socket.

Error UDPReceive::setRouting (  bool  enable  )  [inline, protected]

Reimplemented from Socket.
