public interface Compressor

This interface describes the operations to compress and decompress a file, using a variety of algorithms.

Method Summary

String	compress(InputStream in, OutputStream out) Reads a series of bytes from an inputstream and executes a compression algorithm over those bytes, writing the compressed data to the specified outputStream.
String	decompress(InputStream in, OutputStream out) Reads a series of bytes from compressed data and executes a decompression algorithm over those bytes, writing the decompressed data to the specified outputStream.
