RemoteWrapper

class lsst.ts.watcher.RemoteWrapper(remote, topic_names)

Bases: object

Simple access to the current value of a specified set of topics.

The wrapper uses the same attribute names as lsst.ts.salobj.Remote, but the wrapper’s attributes return the current value of the topic. For example remote_wrapper.evt_summaryState returns remote.evt_summaryState.get().

Parameters
remotelsst.ts.salobj.Remote

Remote to wrap.

topic_nameslist [str]

List of names of topics to wrap, with an evt_ or tel_ prefix.

Raises
ValueError

If a name in topic_names is neither the name of an event nor a telemetry topic.

Notes

The intent is to offer each BaseRule simple access to the current value of the topics it needs, while hiding access to other topics and to methods of topics that BaseRule should not use, such as next.
