ophyd.status.MoveStatus

class ophyd.status.MoveStatus(positioner, target, *, start_ts=None, **kwargs)

Track the state of a movement from some initial to final “position”.

The position could a physical position, a “position” in a pseudo-space, a temperature, etc. This constraint allows richer support for progress bars, including progress updates and an ETA.

Parameters:

positionerPositioner

targetfloat or array-like

Target position

donebool, optional

Whether or not the motion has already completed

successbool, optional

If motion has already completed, the status of that motion

start_tsfloat, optional

The motion start timestamp

timeoutfloat, optional

The default timeout to use for a blocking wait, and the amount of time to wait to mark the motion as failed

settle_timefloat, optional

The amount of time to wait between motion completion and running callbacks

Attributes:

posPositioner

targetfloat or array-like

Target position

donebool

Boolean indicating whether associated operation has completed.

start_tsfloat

The motion start timestamp

finish_tsfloat

The motion completd timestamp

finish_posfloat or ndarray

The final position

successbool

Boolean indicating whether associated operation has completed.
