fesa::FieldSynchroManager::commitModifiedFieldSynchronization ( )

Sets toBeSync flag of fields for the slot and multiplexing context that is registered in the map recentlyModifiedFields_. After the setting of the flag the field, slot and multiplexing context combination is deleted from the map.

Sets toBeSync flag of fields, for all the multiplexing contexts, that are registered in the map recentlyModifiedFields_. After the setting of the flag, the field, slot and multiplexing context combination is deleted from the map.

Parameters:

pContext

multiplexing context of set method
