Detailed Description

Listens to the IPC central if messages have arrived, managed by IPCRelay instances.

Author:

David Rijsman, rijsman@email.arc.nasa.gov Class IPCRelayListener

The listeners listens for IPCCommunicationRelayListener::getListenMilliSeconds for events that have been subscribed to. If no events have been received we will listen again if we have not shut-down the listener.

Member Function Documentation

int IDEA::IPCCommunicationRelayListener::activate (  long    flags = THR_NEW_LWP|THR_JOINABLE|THR_INHERIT_SCHED, int    n_threads = 1, int    force_active = 0, long    priority = ACE_DEFAULT_THREAD_PRIORITY, int    grp_id = -1, ACE_Task_Base *    task = 0, ACE_hthread_t    thread_handles[] = 0, void *    stack[] = 0, size_t    stack_size[] = 0, ACE_thread_t    thread_ids[] = 0 )

Activates the listener; Hard-coded to be limited to one thread. Will return -1 in case of an error. We need to be connected before we activate the listener.

IPCCommunicationRelayListener*& IDEA::Singleton< IPCCommunicationRelayListener >::getInstance (    )  [inline, static, protected, inherited]

The instance. This pattern is used to prevent "static initialization order fiasco" (Google this for better understanding)

int IDEA::IPCCommunicationRelayListener::getListenMilliSeconds (    )  const [inline]

Returns the number of milliseconds we block the thread before we check if we should end the life-cycle of the thread.

IPCCommunicationRelayListener* IDEA::Singleton< IPCCommunicationRelayListener >::instance (    )  [inline, static, inherited]

bool IDEA::IPCCommunicationRelayListener::isActive (    )  const [inline]

Returns true if the invoking listeners is active (listening).

void IDEA::Singleton< IPCCommunicationRelayListener >::release (    )  [inline, static, protected, inherited]

void IDEA::IPCCommunicationRelayListener::shutDown (    )

Shutsdown (de-activates) the invoking listener.

int IDEA::IPCCommunicationRelayListener::svc (  void    )  [private]

Main thread function which does the actual listening.
