TarBZip2Driver

public TarBZip2Driver(String charset,
                      Icon openIcon,
                      Icon closedIcon,
                      int inBlockSize)

Constructs a new TAR.BZ2 driver.

Parameters:

inBlockSize - The compression block size to use when writing a BZIP2 output stream.

Throws:

IllegalArgumentException - If inBlockSize is not in the range [1..9].

Method Detail

getLevel

public final int getLevel()

Returns the value of the property inBlockSize which was provided to the constructor.

createInputStream

protected InputStream createInputStream(Archive archive,
                                        ReadOnlyFile rof)
                                 throws IOException

Returns a newly created and verified CBZip2InputStream. This method performs a simple verification by computing the checksum for the first record only. This method is required because the CBZip2InputStream unfortunately does not do sufficient verification!

Overrides:

createInputStream in class TarDriver

Throws:

IOException

createTarOutputArchive

protected TarOutputArchive createTarOutputArchive(Archive archive,
                                                  OutputStream out,
                                                  TarInputArchive source)
                                           throws IOException

Overrides:

createTarOutputArchive in class TarDriver

Throws:

IOException
