Method Detail

setLevel

public void setLevel(int compressionLevel)

Description copied from interface: IOutFeatureSetLevel

Set compression level:

• 0 - Copy mode (no compression)
• 1 - Fastest
• 3 - Fast
• 5 - Normal
• 7 - Maximum
• 9 - Ultra

Note, that the meaning of compression level can differ through out different archive formats.

Specified by:

setLevel in interface IOutFeatureSetLevel

Parameters:

compressionLevel - compression level to set. -1 - use default

setHeaderEncryption

public void setHeaderEncryption(boolean enabled)
                         throws SevenZipException

Description copied from interface: IOutFeatureSetEncryptHeader

Enable/disable header encryption for password protected archives. If enabled, the archive header containing file names and other metadata will be encrypted as well.

Note: Implement ICryptoGetTextPassword in your callback class to turn on the encryption.

Specified by:

setHeaderEncryption in interface IOutFeatureSetEncryptHeader

Parameters:

enabled - true enable header encryption, otherwise false

Throws:

SevenZipException - in error case. If this method ends with an exception, the current operation will be reported to 7-Zip as failed. There are no guarantee, that there are no further call back methods will get called. The first and last thrown exceptions will be saved and thrown later on from the originally called method such as ISevenZipInArchive.extract() or SevenZip.openInArchive(). Up to four exceptions depending on the situation can be saved for further analysis. See SevenZipException and SevenZipException.printStackTraceExtended() for details.

setSolid

public void setSolid(boolean solid)

Set solid archive option. If deactivated, some other solid options like 'solid files' will take no effect.

Specified by:

setSolid in interface IOutFeatureSetSolid

Parameters:

solid - true - use default configuration, false - deactivate solid block mode

setSolidFiles

public void setSolidFiles(int countOfFilesPerBlock)

Put specified count of files in a single solid block. See IOutFeatureSetSolid.setSolid(boolean).

Specified by:

setSolidFiles in interface IOutFeatureSetSolid

Parameters:

countOfFilesPerBlock - count of files per solid block. -1 - use default configuration

See Also:

IOutFeatureSetSolid.setSolid(boolean)

setSolidSize

public void setSolidSize(long countOfBytesPerBlock)

Put specified count of bytes in a single solid block. See IOutFeatureSetSolid.setSolid(boolean).

Specified by:

setSolidSize in interface IOutFeatureSetSolid

Parameters:

countOfBytesPerBlock - count of bytes per solid block. -1 - use default configuration.

See Also:

IOutFeatureSetSolid.setSolid(boolean)

setSolidExtension

public void setSolidExtension(boolean solidExtension)

Put all files with the same extension following each other in the order of packing in a solid block. See IOutFeatureSetSolid.setSolid(boolean).

Specified by:

setSolidExtension in interface IOutFeatureSetSolid

Parameters:

solidExtension - true - activate this feature, false - use default configuration

See Also:

IOutFeatureSetSolid.setSolid(boolean)

setThreadCount

public void setThreadCount(int threadCount)

Set number of threads to use.

Specified by:

setThreadCount in interface IOutFeatureSetMultithreading

Parameters:

threadCount - number of threads to use,
0 - match count of threads to the count of the available processors,
-1 - use default value
