Member Function Documentation

PersistencyManager * fesa::PersistencyManager::getInstance ( )
static

Get the instance of this class (unique in the system). The unique instance will be created the first time the function is called.

Returns
The instance of this class
void fesa::PersistencyManager::queueTrigger ( const std::string &  className)

Queue a persistency trigger. This function is intended to be used by the trigger producers.

Parameters
classNameThe name of the FESA class whose data are queued for storing
bool fesa::PersistencyManager::registerPersistencyUnit ( std::auto_ptr< PersistencyUnit >  persistencyUnit)

Registers a new persistency unit and checks that it can be persisted.

Parameters
persistencyUnitA persistency unit
Returns
true if the persistency unit can be persisted or doesn't need to be persisted; false if it must be persisted but cannot.
void fesa::PersistencyManager::trigger ( const std::string &  className)

Trigger the procedure to store the persistent data into the persistency file. This function is intended for the so called 'manual' persistency triggering.

Parameters
classNameThe name of the FESA class whose data are to be stored
void fesa::PersistencyManager::triggerWithDelay ( const std::string &  className)

Trigger the procedure to store the persistent data into the persistency file. This function is intended for persistency triggering after a setting. The data storing procedure will start only if there are no settings for the given time interval. The delay is specified in fesa.cfg.

Parameters
classNameThe name of the FESA class whose data are to be stored
