Member Function Documentation

◆ Clone()

CZipCompressor::COptions * ZipArchiveLib::CDeflateCompressor::COptions::Clone ( ) const

inlinevirtual

Clones the current options object.

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

Implements CZipCompressor::COptions.

◆ GetType()

int ZipArchiveLib::CDeflateCompressor::COptions::GetType ( ) const

inlinevirtual

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.

Implements CZipCompressor::COptions.

Member Data Documentation

◆ m_bCheckLastBlock

bool ZipArchiveLib::CDeflateCompressor::COptions::m_bCheckLastBlock

Enables or disables checking, if the compressed data ends with an end-of-stream block. This should be enabled to protect against malformed data. true, if the checking of the last block should be enabled; false otherwise.

◆ m_bCreateOffsetsArray

bool ZipArchiveLib::CDeflateCompressor::COptions::m_bCreateOffsetsArray

Specifies whether the CZipCompressor::COffsetsArray is created while creating synchronization blocks. true, if the offsets array should be created; false otherwise.

Note: Normally, this value should be always set to true.

See also: Creating Seekable Compressed Data; CDeflateCompressor::GetOffsetsArray; m_iSyncRatio

◆ m_iSyncRatio

int ZipArchiveLib::CDeflateCompressor::COptions::m_iSyncRatio

Determines how often synchronization blocks are created.

0 - disables creation of synchronization blocks,
the larger the value, the rarer the synchronization blocks are created and the better the compression ratio is.

Note: This setting has no effect on stored or encrypted data. The synchronization blocks will not be created in these cases regardless of the value set.; You can use CZipCompressor::COffsetsArray::GetStatistics to determine the best value.
