Interface VExtendedAlarm

All Superinterfaces:

VType

public interface VExtendedAlarm
extends VType

Extended alarm information. This supplements the alarm information given with scalar and array pvs, by showing all the possible alarm conditions specific to a device, and which ones are active at the moment.

The data type on the wire will look significantly different. The name and severity of each conditions don't typically change and are considered metadata. The actual alarm state (which ones are on or off) and the error message are what changes at each notification.
