Detailed Description

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

Definition at line 43 of file UDPConvergenceLayer.h.

Constructor & Destructor Documentation

	)

Constructor

Parameters

[in]	bind_addr	The address to bind.
[in]	port	The udp port to use.

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 451 of file UDPConvergenceLayer.cpp.

References ibrcommon::vsocket::down().

Here is the call graph for this function:

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.

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.

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.
