WindowedMultiInOut

Flush all outlets. Returns true if ''all'' of them have been successfully flushed.

Whether an inlet constitutes a crucial input whose closure should result in stage termination.

The number of frames available for input window processing. This is used before calling readIntoWindow.

Whether crucial inputs are done and thus the output should be flushed and the stage terminated.

The number of frames available for output window processing. This is used before calling writeFromWindow.

Whether all outputs are done and thus the stage should be terminated.

Called after a window has been fully read in.

Reads in a number of frames.

The number of frames to read in per window.

Tries to prepare the parameters for the next window. If successful, returns true otherwise false. If successful, it must be possible to successively call readWinSize. Most likely, the implementation will allocate an internal window buffer here.

Writes out a number of frames.

The number of frames to write out per window. This is polled once after processWindow.

Invoked by Akka after processing of external events stopped because the operator is about to stop or fail. Calls stopped and then removes the node from the control.

Final so we don't accidentally place code here. In order to initialize state, use NodeHasInitImpl and implement init.
