class TaurusDevState(*values)

  Enumeration of possible states of `taurus.core.TaurusDevice` objects. This is returned, e.g. by `TaurusDevice.state()`.

  The description of the values of this enumeration is:

  - Ready: the device can be operated by the user and could even be involved in some operation.

  - NotReady: the device can not be operated by the user (e.g. due to still being initialized, or due to a device failure,…)

  - Undefined: it is not possible to retrieve a coherent state from the device (e.g. due to communication, or to contradictory internal states, …)

  Import from `taurus.core` as:

      from taurus.core import TaurusDevState

  NotReady = 2
  Ready = 1
  Undefined = 4
