Enum MetricData

java.lang.Object
  java.lang.Enum<MetricData>

All Implemented Interfaces:

Serializable, Comparable<MetricData>

public enum MetricData
extends Enum<MetricData>

An enum to acces data from a Counter based on the property name. Can be used to avoid reflection on Counter implementation when requesting data and undesirable exposure of internals.

example :

 String property = httpServletRequest.getParameter( "property" );

 Double data = MetricData.valueOf( property ).value( metric );

values

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

Returns:

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

valueOf

public static MetricData 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
