pass "mode" into ophyd methods #4

Closed jrmlhermitte closed 2 years ago

jrmlhermitte commented 6 years ago

A while back I made these changes (in a different local branch) https://github.com/NSLS-II/bluesky/compare/master...jrmlhermitte:streaming-read2#diff-918281cac085be7995578c4c2c57cd4eR396

We should eventually extend to make the RunEngine stream aware. Pieces of this code could be used and tested here: https://github.com/NSLS-II/bluesky/compare/master...jrmlhermitte:streaming-read2#diff-918281cac085be7995578c4c2c57cd4eR396

The main idea is that right now it's assumed that the same detector read in different streams yields a dictionary with the same keys. However, with a potential change where detectors in different modes can yield different results (for example, say a mode that ignores the stats plugins), this won't be true. (The OEP for this is here ).

This should be an easy add.

For clarity, the descriptor cache is already stream aware, this is the cache of calling obj.describe() .
