Stream demuxing block to demultiplex one stream into N output streams.

Demuxes a stream producing N outputs streams that contains n_0 items in the first stream, n_1 items in the second, etc., and repeats. Tags are propagated. The number of items in each output stream is specified using the lengths parameter like so [n_0, n_1, ..., n_N-1].

Example:
lengths = [2, 3, 4]

input stream = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, ...]
output_stream_0 = [0, 1, 9, 10, ...]
output_stream_1 = [2, 3, 4, 11, ...]
output_stream_2 = [5, 6, 7, 8, ...]

Parameters

Lengths
a vector (list/tuple) specifying the number of items to copy to each output stream.
Num outputs
Number of output streams.

Example Flowgraph

This flowgraph shows the Stream Demux block demuxing an input stream into three output streams with lengths = [2, 3, 4].

The block will put 2 items into the first output stream, 3 items into the second output stream, 4 items into the third output stream, and repeat. Notice that tags are preserved.
