public class AdaptiveReceiveBufferSizePredictor extends Object implements ReceiveBufferSizePredictor
ReceiveBufferSizePredictorthat automatically increases and decreases the predicted buffer size on feed back.
It gradually increases the expected number of readable bytes if the previous read fully filled the allocated buffer. It gradually decreases the expected number of readable bytes if the read operation was not able to fill a certain amount of the allocated buffer two times consecutively. Otherwise, it keeps returning the same prediction.

minimum- the inclusive lower bound of the expected buffer size
initial- the initial buffer size when no feed back was received
maximum- the inclusive upper bound of the expected buffer size
