Class DoubleHistogram

java.lang.Object

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

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

All Implemented Interfaces:

Histogram

Direct Known Subclasses:

DoubleDynamicHistogram

public class DoubleHistogram
extends AbstractStaticHistogram

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

Since:

0.5.5
