C# Class Lucene.Net.Documents.CompressionTools

Simple utility class providing static methods to compress and decompress binary data for stored fields. This class uses java.util.zip.Deflater and Inflater classes to compress and decompress, which is the same format previously used by the now deprecated Field.Store.COMPRESS.
