Method Detail

init

public void init(int type,
                 int level)

Description copied from interface: SshCompression

Initialize the compression.

Specified by:

init in interface SshCompression

Parameters:

type - the mode of the compression, should be either INFLATER or DEFLATER

level - the level of compression

compress

public byte[] compress(byte[] data,
                       int start,
                       int len)
                throws IOException

Description copied from interface: SshCompression

Compress a block of data.

Specified by:

compress in interface SshCompression

Parameters:

data - the data to compress

start - the offset of the data to compress

len - the length of the data

Returns:

the compressed data with any uncompressed data at the start remaining intact.

Throws:

IOException

uncompress

public byte[] uncompress(byte[] data,
                         int start,

                  throws IOException

Description copied from interface: SshCompression

Uncompress a block of data.

Specified by:

uncompress in interface SshCompression

Parameters:

data - the data to uncompress

start - the offset of the data to uncompress

len - the length of the data

Returns:

the uncompressed data with any data not compressed at the start remaining intact.

Throws:

IOException
