Class IntStaticHistogram

java.lang.Object

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

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

All Implemented Interfaces:

Histogram, IntHistogram

Direct Known Subclasses:

IntDynamicHistogram

public class IntStaticHistogram
extends AbstractStaticHistogram
implements IntHistogram

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