All Implemented Interfaces:

DoubleHistogram, Histogram

Direct Known Subclasses:

DoubleDynamicHistogram

public class DoubleStaticHistogram
extends AbstractStaticHistogram
implements DoubleHistogram

Histogram class storing double values. The histogram will start with "bin" bins, but it can grow dynamically to the left and right.
