poll(single=True, value=None, time=None, error=None)

Notify listeners when the attribute has been polled

push_event(event)

Method invoked by the PyTango layer when an event occurs. It propagates the event to listeners and delegates other tasks to specific handlers for different event types.

property range

read(cache=True)

Returns the current value of the attribute.

If cache is not False, or expired, or the attribute has events active, then it will return the local cached value. Otherwise it will read the attribute value from the tango device.

The cached value expires if it is older than the value (im ms) passed as the cache argument or the polling period if cache==True (default). If the cache is expired a reading will be done just as if cache was False.

Parameters:

cache (bool or float) – use cache value or make readout, eventually pass a cache’s expiration period in milliseconds

Returns:

attribute value

Return type:

TangoAttributeValue

removeListener(listener)

Remove a TaurusListener from the listeners list. If polling enabled and it is the last element the stop the polling timer. If the listener is not registered nothing happens.
