Detailed Description
Management of FESA classes' persistency.
Member Function Documentation
|
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::persistAllNow | ( | ) |
Persists all the persistent data. This is a blocking call, it returns when data has been persisted.
- Exceptions
-
FesaException in cases such as an impossibility to write the xml, or to rename the temporary file
| bool fesa::PersistencyManager::registerPersistencyUnit | ( | std::auto_ptr< PersistencyUnit > | persistencyUnit | ) |
Registers a new persistency unit and checks that it can be persisted.
- Parameters
-
persistencyUnit A 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
-
className The 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 sets for a configured time interval. The delay is specified in fesa.cfg.
- Parameters
-
className The name of the FESA class whose data are to be stored
