RemoteInfo#

class lsst.ts.watcher.RemoteInfo(name, index, callback_names=None, poll_names=None, index_required=True)#

Bases: object

Information about a remote SAL component.

Parameters:

  • name (str) – Name of SAL component.

  • index (int) – SAL component index; use 0 if the component is not indexed.

  • callback_names (list [str], optional) – Names of telemetry or event topics for which the rule is called when a sample is read. If None then no such topics. Each name must include prefix evt_ or tel_ for event or telemetry. For example [“evt_FilterChangeInPosition”, “evt_TrackingTarget”]

  • poll_names (list [str], optional) – Names of telemetry or event topics which are available to the rule, but do not trigger a rule callback. If None then no such topics. Each name must include prefix evt_ or tel_ for event or telemetry.

  • index_required (bool, optional) – If the component is indexed, is a non-zero index required? Defaults to True, since it is rare for a rule to be able to handle more than one instance of a CSC.
