Field Detail

inputStream

protected StreamInput inputStream

stream to be decompressed

cfgFullReads

protected boolean cfgFullReads

Flag that indicates whether we force full reads (reading of as many bytes as requested), or 'optimal' reads (up to as many as available, but at least one). Default is false, meaning that 'optimal' read is used.
