Package org.apache.hadoop.io.compress

Interface Summary

Interface	Description
CompressionCodec	This class encapsulates a streaming compression/decompression pair.
Compressor	Specification of a stream-based 'compressor' which can be plugged into a CompressionOutputStream to compress data.
Decompressor	Specification of a stream-based 'de-compressor' which can be plugged into a CompressionInputStream to compress data.
DirectDecompressionCodec	This class encapsulates a codec which can decompress direct bytebuffers.
DirectDecompressor	Specification of a direct ByteBuffer 'de-compressor'.
SplittableCompressionCodec	This interface is meant to be implemented by those compression codecs which are capable to compress / de-compress a stream starting at any arbitrary position.

Class Summary

Class	Description
BlockCompressorStream	A CompressorStream which works with 'block-based' based compression algorithms, as opposed to 'stream-based' compression algorithms.
BlockDecompressorStream	A DecompressorStream which works with 'block-based' based compression algorithms, as opposed to 'stream-based' compression algorithms.
BZip2Codec	This class provides output and input streams for bzip2 compression and decompression.
CodecPool	A global compressor/decompressor pool used to save and reuse (possibly native) compression/decompression codecs.
CompressionCodec.Util
CompressionCodecFactory	A factory that will find the correct codec for a given filename.
CompressionInputStream	A compression input stream.
CompressionOutputStream	A compression output stream.
CompressorStream
DecompressorStream
DefaultCodec
DeflateCodec	Alias class for DefaultCodec to enable codec discovery by 'deflate' name.
GzipCodec	This class creates gzip compressors/decompressors.
GzipCodec.GzipOutputStream	A bridge that wraps around a DeflaterOutputStream to make it a CompressionOutputStream.
Lz4Codec	This class creates lz4 compressors/decompressors.
SnappyCodec	This class creates snappy compressors/decompressors.
SplitCompressionInputStream	An InputStream covering a range of compressed data.

Enum Summary

Enum	Description
SplittableCompressionCodec.READ_MODE	During decompression, data can be read off from the decompressor in two modes, namely continuous and blocked.

Annotation Types Summary

Annotation Type	Description
DoNotPool	This is a marker annotation that marks a compressor or decompressor type as not to be pooled.
