Class ArrayOfDoublesCompactSketch

java.lang.Object

org.apache.datasketches.tuple.arrayofdoubles.ArrayOfDoublesSketch

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 TupleUnion, TupleIntersection or TupleAnotB. A CompactTupleSketch consists of a compact list (i.e. no intervening spaces) of hash values, a corresponding list of double values, and a value for theta. The lists may or may not be ordered. It is read-only.

Method Summary

Modifier and Type	Method	Description
int	getCurrentBytes()	For compact sketches this is the same as getMaxBytes().
int	getMaxBytes()	Returns the maximum number of bytes for this sketch when serialized.
