Re: [Discuss-gnuradio] Hier block I/O's

[Marcus Müller]

The port labels (for stream ports, for message ports it's different) are a concept that only exists in the context of GRC, so you can't really access them from within a python application.

Suggestion: implement a get_port_descriptor(self, port_number) method, that returns a string describing that port.

Hi Vanush,

I don't really understand your question. Could you rephrase/elaborate?
Also, what would you want to do with that reference?
