Detailed Description

This class provides the feature of offsetting existing storage instances.

Member Function Documentation

static AutoPtr<StorageOffsetter> Celartem::StorageOffsetter::create	(	Storage *	inStorage,
		uint64_t	inOffset
	)

static

This method creates offsetted Storage.

Parameters

inStorage	A storage.
inOffset	Offset in bytes.

virtual void Celartem::StorageOffsetter::offset ( size_t inAdditionalOffset )

pure virtual

Additionally offset the storage.
This method also conditions the current position according to the offset change.

Parameters

inAdditionalOffset Additional offset.
