void dtn::core::FragmentManager::__cancellation ( ) throw ()

virtual

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

Implements dtn::daemon::IndependentComponent.

Definition at line 58 of file FragmentManager.cpp.

References ibrcommon::Queue< T >::abort().

Here is the call graph for this function:

void dtn::core::FragmentManager::componentDown ( ) throw ()

virtual

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::core::FragmentManager::componentRun ( ) throw ()

virtual

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