All Implemented Interfaces:

Closeable, AutoCloseable

@Deprecated
public class SnappyInputStream
extends AbstractSnappyInputStream

Deprecated.

Prefer the use of SnappyFramedInputStream which implements the standard x-snappy-framed specification.

This class implements an input stream for reading Snappy compressed data of the format produced by SnappyOutputStream.

NOTE:This implementation cannot read compressed data produced by SnappyFramedOutputStream.
