Class FloatStaticHistogram

java.lang.Object

de.lmu.ifi.dbs.elki.utilities.datastructures.histogram.AbstractStaticHistogram

de.lmu.ifi.dbs.elki.utilities.datastructures.histogram.FloatStaticHistogram

All Implemented Interfaces:

FloatHistogram, Histogram

Direct Known Subclasses:

FloatDynamicHistogram

public class FloatStaticHistogram
extends AbstractStaticHistogram
implements FloatHistogram

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