self
Description copied from class:MapMakerInternalMap.SegmentReturnsthisup-casted to the specificMapMakerInternalMap.Segmentimplementation typeS.This method exists so that the
MapMakerInternalMap.Segmentcode can be generic in terms ofS, the type of the concrete implementation.- Specified by:

getKeyReferenceQueueForTesting
ReferenceQueue<K> getKeyReferenceQueueForTesting()Description copied from class:MapMakerInternalMap.SegmentUnsafely extracts the key reference queue used by this segment. -
getValueReferenceQueueForTesting

castForTesting
public MapMakerInternalMap.WeakKeyWeakValueEntry<K,V> castForTesting(MapMakerInternalMap.InternalEntry<K, V, ?> entry) Description copied from class:MapMakerInternalMap.SegmentUnsafe cast of the given entry toE, the type of the specificMapMakerInternalMap.InternalEntryimplementation type.This method is provided as a convenience for tests. Otherwise they'd need to be knowledgable about all the implementation details of our type system trickery.
