Detailed Description

This class implement a ConvergenceLayer for UDP/IP. Each bundle is sent in exact one UDP datagram.

Member Function Documentation

void dtn::net::UDPConvergenceLayer::__cancellation ( ) throw ( )

protectedvirtual

This method is called after componentDown() and should should guarantee that blocking calls in componentRun() will unblock.

Implements dtn::daemon::IndependentComponent.

Definition at line 486 of file UDPConvergenceLayer.cpp.

void dtn::net::UDPConvergenceLayer::componentDown ( ) throw ( )

protectedvirtual

This method is called if the component should stop. Clean-up code should be inserted here.

Implements dtn::daemon::IndependentComponent.

Definition at line 433 of file UDPConvergenceLayer.cpp.

References dtn::core::BundleCore::getDiscoveryAgent(), dtn::core::BundleCore::getInstance(), and dtn::net::DiscoveryAgent::unregisterService().

Referenced by ~UDPConvergenceLayer().

Here is the call graph for this function:

void dtn::net::UDPConvergenceLayer::componentRun ( ) throw ( )

protectedvirtual

This is the run method. The component should loop in there until componentDown() or __cancellation() is called.

Implements dtn::daemon::IndependentComponent.

Here is the call graph for this function:

void dtn::net::UDPConvergenceLayer::componentUp ( ) throw ( )

protectedvirtual

Is called in preparation of the component. Before componentRun() is called.
