All Implemented Interfaces:

Histogram, ShortHistogram

Direct Known Subclasses:

ShortDynamicHistogram

public class ShortStaticHistogram
extends AbstractStaticHistogram
implements ShortHistogram

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