org.apache.datasketches.tuple.arrayofdoubles.ArrayOfDoublesCompactSketch

public abstract class ArrayOfDoublesCompactSketch extends ArrayOfDoublesSketch
Top level compact tuple sketch of type ArrayOfDoubles. Compact sketches are never created directly. They are created as a result of the compact() method on a QuickSelectSketch or the getResult() method of a set operation like Union, Intersection or AnotB. Compact sketch consists of a compact list (i.e. no intervening spaces) of hash values, corresponding list of double values, and a value for theta. The lists may or may not be ordered. A compact sketch is read-only.
