◆ loadFromStore()

CDataCacheRevision::LockGuard swift::misc::CDataCacheSerializer::loadFromStore	(	const swift::misc::CValueCachePacket &	baseline,
		bool	defer = `false`,
		bool	pinsOnly = `false`
	)

Load values from persistent store. Called once per second. Also called by saveToStore, to ensure that remote changes to unrelated values are not lost.

Parameters

baseline	A snapshot of the currently loaded values, taken when the load is queued.
defer	Whether to defer applying the changes. Used when called by saveToStore.
pinsOnly	Only load pinned values.

Returns: Usually ignored, but can be held in order to retain the revision file lock.
