Crc ( )

Crc

(

)

const [inline]

Return the CRC - used for checking validity of the archive

Return Value: the CRC value

InitializeL ( CEZZStream & )

void

InitializeL

(

aZStream

)

[virtual]

Reimplemented from CEZFileBufferManager::InitializeL(CEZZStream &)

Initialise the stream with input and output buffers and starts reading

Parameters
aZStream	the stream to initialise

NeedInputL ( CEZZStream & )

void

NeedInputL

(

aZStream

)

[virtual]

Reimplemented from CEZFileBufferManager::NeedInputL(CEZZStream &)

Set the stream's input buffer and starts reading

Parameters
aZStream	the steam whose input buffer to set

NewL ( RFile &, RFile &, TInt )

CEZFileToGzipBM *	NewL	(	RFile &	aInput,
			RFile &	aOutput,
			TInt	aBufferSize
		)	[static]

Reimplemented from CEZFileBufferManager::NewL(RFile &,RFile &,TInt)

Creates a new CEZFileBufferManager object

Parameters
aInput	the input file
aOutput	the output file
aBufferSize	the required size of the buffers

Return Value: the new CEZFileBufferManager object

NewLC ( RFile &, RFile &, TInt )

CEZFileToGzipBM *	NewLC	(	RFile &	aInput,
			RFile &	aOutput,
			TInt	aBufferSize
		)	[static]

Reimplemented from CEZFileBufferManager::NewLC(RFile &,RFile &,TInt)

Creates a new CEZFileBufferManager object and leave it on the CleanupStack

Parameters
aInput	the input file
aOutput	the output file
aBufferSize	the required size of the buffers

Return Value: the new CEZFileBufferManager object, on the CleanupStack
