ska_tmc_sdpsubarrayleafnode.manager.component_manager module

This module provided a reference implementation of a BaseComponentManager.

It is provided for explanatory purposes, and to support testing of this package.

class ska_tmc_sdpsubarrayleafnode.manager.component_manager.SdpSLNComponentManager(*args: Any, **kwargs: Any)

Bases: ska_tmc_common.tmc_component_manager.ska_tmc_common.tmc_component_manager.TmcLeafNodeComponentManager._name

A component manager for The SDP Subarray Leaf Node component.

It supports:

• Monitoring its component, e.g. detect that it has been turned off or on

device_failed(exception)

Return the list of the checked monitored devices

Returns

list of the checked monitored devices

get_device()

Return the device info our of the monitoring loop with name dev_name

Parameters

None –

Returns

a device info

Return type

DeviceInfo

stop()

update_device_info(sdp_subarray_dev_name)

update_device_obs_state(obs_state)

Update a monitored device obs state, and call the relative callbacks if available

Parameters

• dev_name (str) – name of the device

• obs_state (ObsState) – obs state of the device

class ska_tmc_sdpsubarrayleafnode.manager.SdpSLNEventReceiver(*args: Any, **kwargs: Any)

Bases: ska_tmc_common.event_receiver.ska_tmc_common.event_receiver.EventReceiver._name

The SdpSLNEventReceiver class has the responsibility to receive events from the sub devices managed by the Sdp Subarray Leaf Node.

The ComponentManager uses the handle events methods for the attribute of interest. For each of them a callback is defined.
