get

public SevenZFile get()
               throws java.io.IOException

Description copied from interface: IOSupplier

Gets a result.

Returns:

a result

Throws:

java.io.IOException - if an I/O error occurs.

setDefaultName

public SevenZFile.Builder setDefaultName(java.lang.String defaultName)

Sets the default name.

Parameters:

defaultName - the default name.

Returns:

this.

setMaxMemoryLimitKb

public SevenZFile.Builder setMaxMemoryLimitKb(int maxMemoryLimitKb)

Sets the maximum amount of memory in kilobytes to use for parsing the archive and during extraction.

Not all codecs honor this setting. Currently only LZMA and LZMA2 are supported.

Parameters:

maxMemoryLimitKb - the max memory limit in kilobytes.

Returns:

this.

setPassword

public SevenZFile.Builder setPassword(byte[] password)

Sets the password.

Parameters:

password - the password.

Returns:

this.

setPassword

public SevenZFile.Builder setPassword(char[] password)

Sets the password.

Parameters:

password - the password.

Returns:

this.

setPassword

public SevenZFile.Builder setPassword(java.lang.String password)

Sets the password.

Parameters:

password - the password.

Returns:

this.

setSeekableByteChannel

public SevenZFile.Builder setSeekableByteChannel(java.nio.channels.SeekableByteChannel seekableByteChannel)

Sets the input channel.

Parameters:

seekableByteChannel - the input channel.

Returns:

this.

setTryToRecoverBrokenArchives

public SevenZFile.Builder setTryToRecoverBrokenArchives(boolean tryToRecoverBrokenArchives)

Sets whether SevenZFile will try to recover broken archives where the CRC of the file's metadata is 0.

This special kind of broken archive is encountered when mutli volume archives are closed prematurely. If you enable this option SevenZFile will trust data that looks as if it could contain metadata of an archive and allocate big amounts of memory. It is strongly recommended to not enable this option without setting setMaxMemoryLimitKb(int) at the same time.

Parameters:

tryToRecoverBrokenArchives - whether SevenZFile will try to recover broken archives where the CRC of the file's metadata is 0.

Returns:

this.

setUseDefaultNameForUnnamedEntries

public SevenZFile.Builder setUseDefaultNameForUnnamedEntries(boolean useDefaultNameForUnnamedEntries)

Sets whether entries without a name should get their names set to the archive's default file name.

Parameters:

useDefaultNameForUnnamedEntries - whether entries without a name should get their names set to the archive's default file name.

Returns:

this.
