Enum Class DataType

java.lang.Object

java.lang.Enum<DataType>

org.infinispan.jmx.annotations.DataType

All Implemented Interfaces:

Serializable, Comparable<DataType>, Constable

public enum DataType
extends Enum<DataType>

The type of data that is to be collected. This type also effects the way the data is exported for management and for metrics.

Enum Constant Summary

Enum Constants

Enum Constant	Description
HISTOGRAM	Similar to MEASUREMENT, but instead of instantaneous values this provides a histogram of past values.
MEASUREMENT	Numeric data that normally changes over time and it interesting to be exposed as a metric.
TIMER	Similar to HISTOGRAM but the measured values are time durations.
TRAIT	A value of the running system that changes rarely or never.

Method Summary

Modifier and Type	Method	Description
String	toString()
static DataType	valueOf(String name)	Returns the enum constant of this class with the specified name.
static DataType[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

TRAIT

public static final DataType TRAIT

A value of the running system that changes rarely or never. This is exposed as a JMX manageable attribute, but never as a metric.

MEASUREMENT

public static final DataType MEASUREMENT

Numeric data that normally changes over time and it interesting to be exposed as a metric. If this is applied to a non-numeric property it will not be exported as a metric but will still be exported as a JMX manageable attribute.

HISTOGRAM

public static final DataType HISTOGRAM

Similar to MEASUREMENT, but instead of instantaneous values this provides a histogram of past values.

TIMER

public static final DataType TIMER

Similar to HISTOGRAM but the measured values are time durations.

Method Details

values

public static DataType[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static DataType valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

toString

public String toString()

Overrides:

toString in class Enum<DataType>
