Internals of streamSync

This document describes the structure and execution of streamSync, implemented as streamSync function.

stream sync Structure

The streamSync synchronizes all streams by sharing a same end-flag stream. Each input data stream has an end-flag stream. After sync, all output streams share one end-flag stream, and each of them is a duplicate of an input stream. That is to say, before output an end-flag, each ouput stream should output a data from corresponding input stream.

Caution

Applicable conditions. 1. It assumes the input elements in each input stream have the same number. 2. The data type of input stream is same as the one of output.
