Direct Known Subclasses:

ReversePriorityStatisticsMapper

public class PriorityStatisticsMapper
extends AbstractConstantStatisticsMapper

PriorityStatisticsMapper.

It is extremely important to minimise the references in this class, because Lucene keeps a global cache of these objects in a WeakHashMap. If this class has lots of outgoing references, then the retained size increases if this class is held onto, and also the risk of a circular reference back to the key of the WeakHashMap increases, which means it can't be garbage collected.
