QosSet

class lsst.ts.salobj.QosSet(qos_path: str | pathlib.Path, profile_name: str)

Bases: object

QoS profiles for topic, reader and writer.

Parameters

qos_pathstr or pathlib.Path

Path to QoS XML file.

profile_namestr

Profile name; one of “CommandProfile”, “EventProfile”, or “TelemetryProfile”.

Notes

The following QoS should be created elsewhere:

• publisher and subscriber: these depend on the DDS partition name, which is only read when creating the SalInfo object. Also these QoS are the same for all QoS profiles.

• participant: this is the same for all QoS profiles, so there is no point making 3 of them.
