S - source sensor typeTKey - key type in target sensor mapTVal - value type in target sensor mappublic class UpdatingMap<S,TKey,TVal> extends AbstractEnricher implements SensorEventListener<S>
TARGET_SENSOR)
based on the value of another sensor (SOURCE_SENSOR.
The key used defaults to the name of the source sensor but can be specified with KEY_IN_TARGET_SENSOR.
The value placed in the map is the result of applying the function in COMPUTING to the sensor value,
with default behaviour being to remove an entry if null is returned
but this can be overriden by setting REMOVING_IF_RESULT_IS_NULL false.
Entities.REMOVE and Entities.UNCHANGED are also respeced as return values for the computation
(ignoring generics).
Unlike most other enrichers, this defaults to AbstractEnricher.SUPPRESS_DUPLICATES being true
