Member Function Documentation

synchronized void com::cosylab::acs::maci::manager::ComponentInfoTopologicalSortManager::destroy (   )  [inline]

Destroy (terminate thread).

ComponentInfo [] com::cosylab::acs::maci::manager::ComponentInfoTopologicalSortManager::getComponentShutdownOrder (  ContainerInfo  containerInfo  )  [inline]

Get component shutdown order for container. Parameters: containerInfo  valid container's info, if null complete TS is returned. Returns: component shutdown order

void com::cosylab::acs::maci::manager::ComponentInfoTopologicalSortManager::notifyContainerShutdownOrder (  ContainerInfo  containerInfo, int[]  handles )  [inline, private]

Task thats invokes Container::shutdown method. Add new notification. This will keep only the latest one. Parameters: handles  Returns: true if notification is being accepted

synchronized void com::cosylab::acs::maci::manager::ComponentInfoTopologicalSortManager::notifyTopologyChange (  int  containerHandleToNotify  )  [inline]

Notify about (possible) topology change and initiates sorting. Parameters: containerHandleToNotify  container handle to notify.

void com::cosylab::acs::maci::manager::ComponentInfoTopologicalSortManager::requestTopologicalSort (   )  [inline]

Request topological sort.

void com::cosylab::acs::maci::manager::ComponentInfoTopologicalSortManager::run (   )  [inline]

(Sync is clean since activationPendingRWLock is acquired and all notify request is issued only from its reader lock). See also: java.lang.Runnable#run()
