Constructor & Destructor Documentation

◆ OutputDirector()

OutputDirector ( )
private

bring up the framework for handling input/output connections.

Creating this object happens on first access and shouldn't be confused with actually booting up / shutting down this subsystem. Rather, the purpose of the OutputDirector is actively to conduct the Lifecycle of booting, connecting, operating, disconnecting.

Definition at line 58 of file output-director.cpp.

Member Function Documentation

◆ connectUp()

bool connectUp ( )

connect and bring up the external input/output connections, handlers and interface services and the render/playback service.

Returns
true if the output subsystem can be considered operational

Definition at line 72 of file output-director.cpp.

References OutputDirector::isOperational().

+ Here is the call graph for this function:

◆ triggerDisconnect()

void triggerDisconnect ( SigTerm  completedSignal)
noexcept

initiate shutdown of all ongoing render/playback processes and closing of all external input/output interfaces.

Works as an asynchronous operation; the given callback signal will be invoked when the shutdown is complete.

Note
starting a new thread, which might fail. When this happens, the raised exception will cause immediate unconditional termination of the application.

+ Here is the caller graph for this function:

◆ bringDown()

void bringDown ( SigTerm  completedSignal)
private

actually bring down any calculation processes and finally disconnect any external input/output interfaces. This shutdown and cleanup operation is executed in a separate "Output shutdown supervisor" thread and has the liability to bring down the relevant facilities within a certain timespan. When done, the last operation within this thread will be to invoke the callback signal given as parameter.

Note
locks the OutputDirector
