Method Detail

getNextBuffer

Buffer getNextBuffer()
                     throws IOException,
                            InterruptedException

Returns the next Buffer instance of this queue iterator.

If there is currently no instance available, it will return null. This might happen for example when a pipelined queue producer is slower than the consumer or a spilled queue needs to read in more data.

Important: The consumer has to make sure that each buffer instance will eventually be recycled with Buffer.recycle() after it has been consumed.
