Member Function Documentation

void dtn::net::LOWPANConvergenceLayer::__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 317 of file LOWPANConvergenceLayer.cpp.

References _running, and ibrcommon::vsocket::down().

Here is the call graph for this function:

void dtn::net::LOWPANConvergenceLayer::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 199 of file LOWPANConvergenceLayer.cpp.

References ibrcommon::vsocket::destroy(), ibrcommon::JoinableThread::join(), dtn::core::EventDispatcher< E >::remove(), and ibrcommon::JoinableThread::stop().

Referenced by ~LOWPANConvergenceLayer().

Here is the call graph for this function:

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

protectedvirtual

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