CASHInterval
Provides a unique interval represented by its id, a hyper bounding box
representing the alpha intervals, an interval of the corresponding distance,
and a set of objects ids associated with this interval.

CASHIntervalSplit.f_maxima
Caches maximum function values for given intervals, used for better split
performance.
|
private Map<HyperBoundingBox,Map<DBID,Double>> |
CASHIntervalSplit.f_minima
Caches minimum function values for given intervals, used for better split
performance.
