Enum ConsolFun

java.lang.Object
  java.lang.Enum<ConsolFun>
      org.rrd4j.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.

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
