Vector Sink

Stores stream to a vector, useful if you’re running for a short time, for example in a test. You can access that data using snk.data() after tb.run() has completed.

So something like:

tb.run()
time.sleep(10)
my_data = tb.my_vec_snk.data()
print("data: ",my_data)

To extract data from a running flow graph use the probe blocks.

tb.start()
time.sleep(10)
my_data = tb.my_probe_signal.level()
print("data: ",my_data)

Parameters

Reserve Memory for Items

Reserve space in the internal storage for this many items; the internal storage will still grow to accommodate more item if necessary, but setting this to a realistic value can avoid memory allocations during runtime, especially if you know a priori how many items you're going to store.
