Enclosing class:

LazyTemporalAttributeStorage<V>

public static interface LazyTemporalAttributeStorage.ChangeHandler<V>

There is only a single ChangeHandler for each LazyTemporalAttribute.
In a performance point of view, it's usually a good idea here to buffer the requests, in order to reduce the underlying calls granularity.
