All Implemented Interfaces:

Serializable, Comparable<ValueType>

public enum ValueType
extends Enum<ValueType>

The type of a measurement value is used as a base for processing logic on top of the value. Examples:

• A counter is a value that is always increasing, such as energy consumption in electricity meters or packet counts in IP devices. A counter can be validated by checking that it is indeed increasing. A counter cannot be aggregated over time, since it is already an aggregate value. However, it can be summed up over devices.
• A gauge is a sampled value such as "current temperature". Typically, statistics are computed over gauges, such as average, minimas and maximas over time and devices.
• A rate represents a count over a certain time period. Such values are typically added up over time and averaged over devices.

Method Detail

values

public static ValueType[] 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 (ValueType c : ValueType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ValueType 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
