The RecvByteBufAllocator that always yields the same buffer size prediction. This predictor ignores the feed back from the I/O thread.

  • true to stop reading if we think there is no more data. This may save a system call to read from the socket, but if data has arrived in a racy fashion we may give up our maxMessagesPerRead() quantum and have to wait for the selector to notify us of more data.

Deprecated

as a consequence of RecvByteBufAllocator.Handle being deprecated. See corresponding docs for further information.

Creates a new handle. The handle provides the actual operations and keeps the internal information which is required for predicting an optimal buffer capacity.
