Detailed Description

UDP-based receiver

this receiver uses a UDP port to receive packets. It creates a local UDP port, accepting packets from it.

Examples:

subscriber.cc.

Constructor & Destructor Documentation

UDPReceiver::UDPReceiver ( in_port_t  port,
const char *  hostname = NULL,
bool  reuse = true 
)

constructs a UDPReceiver

Parameters:
port port number
hostname externally visible name for this host. Although it is possible for this library to figure out a hostname, the default value is not 100% reliable, especially in cases in which the host uses dynamically-assigned IP addresses, or in the presence of several network interfaces.
reuse determines whether the given port number should be immediately re-used, if recently bound to another application.

Member Function Documentation

virtual size_t UDPReceiver::receive ( char *  ,
size_t   
) throw (CommException) [virtual]

receives a message

Exceptions:
CommException 

Implements Receiver.

virtual void UDPReceiver::shutdown (  )  [virtual]

closes this sender

Reimplemented from Receiver.

virtual string UDPReceiver::uri (  )  [virtual]

URI for this receiver

a URI is an external representation of the point of contact of this receiver. This URI can be used to create senders to contact this receiver.

Implements Receiver.

virtual string& UDPReceiver::uri ( string &   )  [virtual]

exernally visible URI for this receiver

a URI is an external representation of the point of contact of this receiver. This URI can be used to create senders to contact this receiver.

Implements Receiver.
