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 62 of file FragmentManager.cpp.

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.

References dtn::core::EventDispatcher< E >::remove().

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.
