Interface IHistogram2D

  • All Superinterfaces:
    IHistogram, Serializable
    All Known Implementing Classes:
    Histogram2D


    public interface IHistogram2Dextends IHistogram
    A Java interface corresponding to the AIDA 2D Histogram.

    Note All methods that accept a bin number as an argument willalso accept the constants OVERFLOW or UNDERFLOW as the argument, and as a result give the contents of the resulting OVERFLOW or UNDERFLOWbin.
