RemoteInfo¶

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

Information about a remote SAL component.

Parameters:

namestr: Name of SAL component.
indexint: SAL component index; use 0 if the component is not indexed.
callback_nameslist [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_nameslist [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_requiredbool, 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.

Raises:

ValueError: If any name in callback_names or poll_names does not begin with evt_ or tel_.
ValueError: If the same name appears more than once in callback_names + poll_names, in other words, more than once in either list or in both lists taken together.
ValueError: If no callback_names nor poll_names are specified.
ValueError: If index cannot be cast to an int.

Attributes:
