|
CompressionInputStream
A compression input stream.
|
CompressionOutputStream
A compression output stream.
|
Compressor
Specification of a stream-based 'compressor' which can be
plugged into a
CompressionOutputStream to compress data. |
CompressorStream |
Decompressor
Specification of a stream-based 'de-compressor' which can be
plugged into a
CompressionInputStream to compress data. |
DecompressorStream |
DefaultCodec |
SplitCompressionInputStream
An InputStream covering a range of compressed data.
|
SplittableCompressionCodec
This interface is meant to be implemented by those compression codecs
which are capable to compress / decompress a stream starting at any
arbitrary position.
|
SplittableCompressionCodec.READ_MODE
During decompression, data can be read off from the decompressor in two
modes, namely continuous and blocked.
