Functions

assert_configuration

Assert readings from Configurable.

assert_emitted

Assert emitted document generated by running a Bluesky plan

assert_reading

Assert readings from readable.

assert_value

Assert a signal's value and compare it an expected signal.

callback_on_mock_put

For setting a callback when a backend is put to.

get_dtype

Get the runtime dtype from a numpy ndarray type annotation

get_mock_put

Get the mock associated with the put call on the signal.

get_signal_values

Get signal values in bulk.

get_unique

If all values are the same, return that value, otherwise return TypeError

load_device

Plan which loads PVs from a yaml file into a device.

load_from_yaml

Plan that returns a list of dicts with saved signal values from a yaml file.

merge_gathered_dicts

Merge dictionaries produced by a sequence of coroutines.

mock_puts_blocked

observe_value

Subscribe to the value of a signal so it can be iterated from.

reset_mock_put_calls

save_device

Plan that saves the state of all PV's on a device using a sorter.

save_to_yaml

Plan which serialises a phase or set of phases of SignalRWs to a yaml file.

set_and_wait_for_value

Set a signal and monitor it until it has that value.

set_mock_put_proceeds

Allow or block a put with wait=True from proceeding

set_mock_value

Set the value of a signal that is in mock mode.

set_mock_values

Iterator to set a signal to a sequence of values, optionally repeating the sequence.

set_signal_values

Maps signals from a yaml file into device signals.

soft_signal_r_and_setter

Returns a tuple of a read-only Signal and a callable through which the signal can be internally modified within the device.

soft_signal_rw

Creates a read-writable Signal with a SoftSignalBackend.

wait_for_connection

Call many underlying signals, accumulating exceptions and returning them

wait_for_value

Wait for a signal to have a matching value.

walk_rw_signals

Retrieve all SignalRWs from a device.

Classes

AsyncStatus

CalculateTimeout

Sentinel class used to implement myfunc(timeout=CalculateTimeout)

ConfigSignal

DetectorControl

Classes implementing this interface should hold the logic for arming and disarming a detector

DetectorTrigger

Type of mechanism for triggering a detector to take frames

DetectorWriter

Logic for making a detector write data to somewhere persistent (e.g. an HDF5 file).

Device

Common base class for all Ophyd Async Devices.

DeviceCollector

Collector of top level Device instances to be used as a context manager

DeviceVector

Defines device components with indices.

DirectoryInfo

Information about where and how to write a file.

NameProvider

RuntimeSubsetEnum

SubsetEnum

alias of RuntimeSubsetEnum

ShapeProvider

Signal

A Device with the concept of a value, with R, RW, W and X flavours

SignalBackend

A read/write/monitor backend for a Signals

SignalR

Signal that can be read from and monitored

SignalRW

Signal that can be both read and set

SignalW

Signal that can be set

SignalX

Signal that puts the default value

SoftSignalBackend

An backend to a soft Signal, for test signals see MockSignalBackend.

StandardDetector

Useful detector base class for step and fly scanning detectors.

StandardReadable

Device that owns its children and provides useful default behavior.

StaticDirectoryProvider

TriggerInfo

Minimal set of information required to setup triggering on a detector

TriggerLogic

WatchableAsyncStatus

Exceptions

NotConnected

Exception to be raised if a Device.connect is cancelled
