Class LZ4BlockInputStream

Constructor Detail

• LZ4BlockInputStream

  public LZ4BlockInputStream(java.io.InputStream in,
                     LZ4FastDecompressor decompressor,
                     java.util.zip.Checksum checksum,
                     boolean stopOnEmptyBlock)

  Creates a new LZ4 input stream to read from the specified underlying InputStream.

  Parameters:

  in - the InputStream to poll

  decompressor - the decompressor instance to use

  checksum - the Checksum instance to use, must be equivalent to the instance which has been used to write the stream

  stopOnEmptyBlock - whether read is stopped on an empty block

• LZ4BlockInputStream
