Detailed Description

This class creates a virtual Storage based on a existing one. The created Storage cannot be expanded by writeBytes method.

Member Function Documentation

static AutoPtr<PartialStorage> Celartem::PartialStorage::create	(	Storage *	inStorage,
		uint64_t	inOffset,
		uint64_t	inSize,
		bool	inReadOnly
	)			`[static]`

This method creates virtual Storage.

Parameters:

	inStorage	A storage.
	inOffset	Offset in bytes.
	inSize	The size in bytes.
	inReadOnly	`true` if the new storage should be readonly; otherwise `false`.

virtual Storage* Celartem::PartialStorage::getBaseStorage ( ) [pure virtual]

Get underlying storage.
NOTE: Modification to the underlying instance may causes some inconsistency issues.

virtual uint64_t Celartem::PartialStorage::getOffset ( ) const [pure virtual]

Get the offset on the underlying storage instance.

virtual void Celartem::PartialStorage::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.
