Enclosing class:

MultiBinaryLongMap

public class MultiBinaryLongMap.LeftoverLongMapHolder

extends MultiBinaryLongMap.MaskedLongMapHolder

LeftoverLongMapHolder is the MaskedLongMapHolder implementation that is backed by the "real" key tree itself. The MaskedBinaryLongMap instances created by this holder are stored in the upper 32-bits of the underlying key-tree (where the lower 32-bits encode the "slot" info). Additionally, the returned instances contain additional safety checks to ensure that users of the returned BinaryLongMap may not cause keys to be inadvertently (and illegally) added to the MultiBinaryLongMap.

Nested Class Summary

class

MultiBinaryLongMap.LeftoverLongMapHolder.LeftoverMaskedBinaryLongMap LeftoverMaskedBinaryLongMap is a MaskedBinaryLongMap implementation that is backed by the leftover (upper 32) bits in "real" key-tree itself.
