Class DoubleHistogram3D

  • All Implemented Interfaces:
    DoubleIHistogram, DoubleIHistogram3D, java.io.Serializable

    public class DoubleHistogram3D
extends java.lang.Object
implements DoubleIHistogram3D
    A reference implementation of hep.aida.IHistogram3D. The goal is to provide a clear implementation rather than the most efficient implementation. However, performance seems fine - filling 3 * 10^5 points/sec, both using FixedAxis or VariableAxis.
