public interface AlarmQueryProvider
```
This interface can be implemented by an AlarmProvider in order to provide the ability to query alarm status from a different source than the main alarm state model maintained by the gateway.

- Method Detail
  - acknowledge
```
default java.util.Set<java.util.UUID> acknowledge(java.util.Collection<java.util.UUID> uuids,
                                                  EventData ackData)
```
    Default bulk acknowledge implementation
    
    Parameters:
    
    uuids - IDs of alarm events
    
    ackData - Associated data for ack
    
    Returns:
    
    Set of UUIDs that weren't found
  - acknowledge
```
boolean acknowledge(java.util.UUID eventId,
                    EventData ackData)
```
  - query
```
AlarmQueryResult query(AlarmFilter filter)
```
    Queries the status of the alarms, given the filter. Given the filter, the query may not apply at all to this provider- it is the provider's responsibility to determine this. However, even if the query doesn't apply, the provider is expected to return an empty result set, not null.
