virtual IPMStream* ISVGUtils::CreateZipStream ( IDFile const &  file, uint32  mode  )

pure virtual

Method to copy preferences from one interface to another.

Parameters

file	is the input IDFile to create gzip compressed stream.
mode	is OpenMode: kOpenIn = 0x01, kOpenOut = 0x02, kOpenApp = 0x04, kOpenTrunc = 0x08

Returns

gzip compressed stream.

virtual IPMStream* ISVGUtils::CreateZipStream ( IPMStream *  fileStream, uint32  mode  )

pure virtual

Method to copy preferences from one interface to another.

Parameters

fileStream	is the file stream of the file to create gzip compressed stream.
mode	is OpenMode: kOpenIn = 0x01, kOpenOut = 0x02, kOpenApp = 0x04, kOpenTrunc = 0x08

Returns

gzip compressed stream.

virtual bool16 ISVGUtils::IsCompressed ( IPMStream *  fileStream )

pure virtual

Method to check if a file stream is valid gzip compression or not.

Parameters

fileStream

is the file stream to check if it is valid gzip compression or not.

Returns

kTrue if valid gzip compression otherwise kFalse.
