Constructor & Destructor Documentation

Celartem::DiskStorageLock::DiskStorageLock	(	DiskStorage *	inStorage,
		uint64_t	inPos,
		uint64_t	inSize,
		LockMode	inMode = Shared
	)			[inline]

Locks a region of a DiskStorage instance.

Parameters:

	inStorage	A DiskStorage instance to lock a region of.
	inPos	The offset of the region to lock.
	inSize	The size of the region to lock.
	inMode	The lock mode.

Celartem::DiskStorageLock::DiskStorageLock	(	DiskStorage *	inStorage,
		const LockStorageRegion &	inRegion,
		LockMode	inMode = Shared
	)			[inline]

Locks a region of a DiskStorage instance.

Parameters:

	inStorage	A DiskStorage instance to lock a region of.
	inPos	The offset of the region to lock.
	inSize	The size of the region to lock.
	inMode	The lock mode.

Celartem::DiskStorageLock::DiskStorageLock

(

)

[inline]

Initializes the instance without locking a storage region.

Celartem::DiskStorageLock::~DiskStorageLock

(

)

[inline]

Deinitializes the instance. If a region of a storage is locked, the lock is released.

Member Function Documentation

void Celartem::DiskStorageLock::lock	(	DiskStorage *	inStorage,
		const LockStorageRegion &	inRegion,
		LockMode	inMode = Shared
	)			[inline]

Locks a region of a DiskStorage instance.

Parameters:

	inStorage	A DiskStorage instance to lock a region of.
	inRegion	The region to lock. If the length is 0, this method locks all the subsequent bytes starts from offset.
	inMode	The lock mode.

void Celartem::DiskStorageLock::lock	(	DiskStorage *	inStorage,
		uint64_t	inPos,
		uint64_t	inSize,
		LockMode	inMode = Shared
	)			[inline]

Locks a region of a DiskStorage instance.

Parameters:

	inStorage	A DiskStorage instance to lock a region of.
	inPos	The offset of the region to lock.
	inSize	The size of the region to lock. If this is 0, this method locks all the subsequent bytes starts from inPos.
	inMode	The lock mode.

void Celartem::DiskStorageLock::unlock

(

)

[inline]

Releases the locked region. If no region is locked, do nothing.
