MockDome

class lsst.ts.ATDomeTrajectory.MockDome(initial_state)

Bases: lsst.ts.salobj.base_csc.BaseCsc

A very limited fake ATDome CSC

It receives the moveAzimuth command and outputs:

  • azimuthCommandedState event

  • position telemetry.

It does not enforce motion limits.

Parameters
initial_statesalobj.State or int (optional)

The initial state of the CSC. This is provided for unit testing, as real CSCs should start up in State.STANDBY, the default.

Methods Documentation

classmethod add_arguments(parser)

Add arguments to the parser created by make_from_cmd_line.

Parameters
parserargparse.ArgumentParser

The argument parser.

Notes

If you override this method then you should almost certainly override add_kwargs_from_args as well.

classmethod add_kwargs_from_args(args, kwargs)

Add constructor keyword arguments based on parsed arguments.

Parameters
argsargparse.namespace

Parsed command.

kwargsdict

Keyword argument dict for the constructor. Update this based on args. The index argument will already be present if relevant.

Notes

If you override this method then you should almost certainly override add_arguments as well.

async classmethod amain(index, **kwargs)

Make a CSC from command-line arguments and run it.

Parameters
indexint, enum.IntEnum, True, or None

If the CSC is indexed, do one of the following:

  • Specify True to make index a required command-line argument that accepts any nonzero index.

  • Specify an enum.IntEnum class to make index a required command-line argument that only accepts the enum values.

  • Specify a non-zero integer to use that index. This is rare; if the CSC is indexed then the user should usually be allowed to specify the index.

If the CSC is not indexed, specify None or 0.

**kwargsdict, optional

Additional keyword arguments for your CSC’s constructor.

assert_enabled(action='')

Assert that an action that requires ENABLED state can be run.

Parameters
actionstr, optional

Action attempted. Not needed if this is called at the beginning of a do_... method, since the user will know what command was called.

async begin_disable(data)

Begin do_disable; called before state changes.

Parameters
dataDataType

Command data

async begin_enable(data)

Begin do_enable; called before state changes.

Parameters
dataDataType

Command data

async begin_exitControl(data)

Begin do_exitControl; called before state changes.

Parameters
dataDataType

Command data

async begin_standby(data)

Begin do_standby; called before the state changes.

Parameters
dataDataType

Command data

async begin_start(data)

Begin do_start; called before state changes.

Parameters
dataDataType

Command data

async close(exception=None, cancel_start=True)

Shut down, clean up resources and set done_task done.

May be called multiple times. The first call closes the Controller; subsequent calls wait until the Controller is closed.

Subclasses should override close_tasks instead of close, unless you have a good reason to do otherwise.

Parameters
exceptionException, optional

The exception that caused stopping, if any, in which case the self.done_task exception is set to this value. Specify None for a normal exit, in which case the self.done_task result is set to None.

cancel_startbool, optional

Cancel the start task? Leave this true unless calling this from the start task.

Notes

Removes the SAL log handler, calls close_tasks to stop all background tasks, pauses briefly to allow final SAL messages to be sent, then closes the dds domain.

async close_tasks()

Shut down pending tasks. Called by close.

do_closeShutter(data)

This command is not supported.

async do_disable(data)

Transition from State.ENABLED to State.DISABLED.

Parameters

Parameters

do_openShutter(data)

This command is not supported.

do_setAuthList(data)

Parameters
datacmd_setAuthList.DataType

Notes

Add items if the data string starts with “+”, ignoring duplicates (both with respect to the existing items and within the data string). Remove items if the data string starts with “-“, ignoring missing items (items specified for removal that do not exist). Ignore whitespace after each comma and after the +/- prefix.

do_setLogLevel(data)

Set logging level.

Parameters

Parameters
dataDataType

Command data

fault(code, report, traceback='')

Enter the fault state and output the errorCode event.

Parameters

reportstr

Description of the error.

tracebackstr, optional

Description of the traceback, if any.

async handle_summary_state()

Called when the summary state has changed.

Override to perform tasks such as starting and stopping telemetry (example).

Notes

The versions in BaseCsc and ConfigurableCsc do nothing, so if you subclass one of those you do not need to call await super().handle_summary_state().

async implement_simulation_mode(simulation_mode)

Implement going into or out of simulation mode.

Deprecated. See simulation mode for details.

Parameters
simulation_modeint

Requested simulation mode; 0 for normal operation.

Raises
ExpectedError

If simulation_mode is not a supported value.

classmethod make_from_cmd_line(index, **kwargs)

Construct a CSC from command line arguments.

Parameters
indexint, enum.IntEnum, True, or None

If the CSC is indexed, do one of the following:

  • Specify True to make index a required command-line argument that accepts any nonzero index.

  • Specify an enum.IntEnum class to make index a required command-line argument that only accepts the enum values.

  • Specify a non-zero integer to use that index. This is rare; if the CSC is indexed then the user should usually be allowed to specify the index.

If the CSC is not indexed, specify None or 0.

**kwargsdict, optional

Additional keyword arguments for your CSC’s constructor.

Returns
csccls

The CSC.

Notes

To add additional command-line arguments, override add_arguments and add_kwargs_from_args.

async move_azimuth_loop()

Move the dome to the specified azimuth.

put_log_level()

Output the logLevel event.

report_summary_state()

Report a new value for summary_state, including current state.

Subclasses may wish to override for code that depends on the current state (rather than the state transition command that got it into that state).

async set_simulation_mode(simulation_mode)

Set the simulation mode.

Await implement_simulation_mode, update the simulation mode property and report the new value.

Parameters
simulation_modeint

Requested simulation mode; 0 for normal operation.

async start()

Finish constructing the CSC.
