CShiftedFileStore Class Reference

class CShiftedFileStore : public CDirectFileStore

class CShiftedFileStore - this is highly specialized class, derived from CDirectFileStore. It has only one purpose - to make possible creating direct file store instance beginning at the middle of some physical file. It is expected to be used with the new RSC files format: Header + RSC file section + MBM file section.

Constructor & Destructor Documentation

CShiftedFileStore(RFile &)

CShiftedFileStore

(

RFile &

aFile

)

[private]

Constructor. Prevents compiler warnings. Actually, CShiftedFileStore instance is newer created. CFileStore or CDirectFileStore instance is created and downcasted to CShiftedFileStore. It is possible to do that: CShiftedFileStore doesn't have data members at all.

Parameters

RFile & aFile

Member Functions Documentation

FromL(RFile &, TUint)

CShiftedFileStore *	FromL	(	RFile &	aFile,
			TUint	aFileOffset
		)	[static]

CShiftedFileStore::FromL(RFile& aFile, TUint aFileOffset) method. CFileStore::FromL(RFile& aFile,TFileStoreFactoryFunction aFunction) method was used as an origin for the method's source code. The only difference is that RFileBuf::Attach is called with possibly non-zero offset. The original implementation always calls RFileBuf::Attach with zero offset.

Parameters

RFile & aFile
TUint aFileOffset

OpenLC(RFs &, const TDesC &, TUint, TUint)

CShiftedFileStore *	OpenLC	(	RFs &	aFs,
			const TDesC &	aName,
			TUint	aFileMode,
			TUint	aFileOffset
		)	[static]

CShiftedFileStore::OpenLC(RFs& aFs, const TDesC& aName, TUint aFileMode, TUint aFileOffset) method. CFileStore::OpenL(RFs& aFs,const TDesC& aName,TUint aFileMode,const TFileStoreFactoryFunction aFactory[]) method was used as an origin for the method's source code.

Parameters

RFs & aFs
const TDesC & aName
TUint aFileMode
TUint aFileOffset
