virtual COptions* CZipCompressor::COptions::Clone ( ) const

pure virtual

Clones the current options object.

Returns

The cloned object of the same type as the current object.

Implemented in ZipArchiveLib::CBzip2Compressor::COptions, and ZipArchiveLib::CDeflateCompressor::COptions.

virtual int CZipCompressor::COptions::GetType ( ) const

pure virtual

Returns the type of the compressor to which the current options apply.

Returns

The type of the compressor. It can be one of the CompressorType values.

Implemented in ZipArchiveLib::CBzip2Compressor::COptions, and ZipArchiveLib::CDeflateCompressor::COptions.

Member Data Documentation

int CZipCompressor::COptions::m_iBufferSize

The size of the buffer used in compression and decompression operations. By default it is set to cDefaultBufferSize. For the optimal performance of the deflate algorithm it should be set at least to 128kB.
