Enum ConsolFun

  • All Implemented Interfaces:
    Serializable, Comparable<ConsolFun>

    public enum ConsolFun
    extends Enum<ConsolFun>
    Enumeration of available consolidation functions. Note that data aggregation inevitably leads to loss of precision and information. The trick is to pick the aggregate function such that the interesting properties of your data are kept across the aggregation process.

      • AVERAGE

        public static final ConsolFun AVERAGE
        The average of the data points is stored.
      • MIN

        public static final ConsolFun MIN
        The smallest of the data points is stored.
      • MAX

        public static final ConsolFun MAX
        The largest of the data points is stored.
      • LAST

        public static final ConsolFun LAST
        The last data point is used.
      • FIRST

        public static final ConsolFun FIRST
        The fist data point is used.
      • TOTAL

        public static final ConsolFun TOTAL
        The total of the data points is stored.
    • Method Detail

      • values

        public static ConsolFun[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (ConsolFun c : ConsolFun.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static ConsolFun valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
