decompressFirstKV

private void decompressFirstKV(ByteBuffer out,
                               DataInputStream in)
                        throws IOException

Copies the first key/value from the given stream, and initializes decompression state based on it. Assumes that we have already read key and value lengths. Does not set CompressionState.qualifierLength (not used by decompression) or CompressionState.prevOffset (set by the calle afterwards).

Throws:

IOException
