I think gnuradio needs a mux and a demux block. A mux has N inputs and a
set_n method. The mux will only feed the output with the nth input
stream (throw out/ignore the other inputs). A demux has N outputs and a
set_n method. The demux will only feed the nth output with the input
stream.
Has anybody written something like this allready?
No.
I think this should be implemented using the work-in-progress
that Johnathan's doing for hier_block2. It may be about a week too
early to use ;)
How would you go about doing this? I had thought that one could use a
bunch of message sources and sinks, and a thread could facilitate data
transfer for only one source-sink pair. But how could several blocks
with single inputs appear as one block with multiple inputs? Seems like
trouble...
-------
On another note: The original problem was trying to toggle a section of
a running flow graph on and off. The gr.skiphead seems to be able to do
this by starving the data stream for the first n samples. Could there be
a gr.valve block that can starve a data stream based on a boolean flag?
The flag could set by an open/close method (or something to that effect).
Or a block like this exists and I missed it?
