Enum ExperimentalFeature

java.lang.Object

java.lang.Enum<ExperimentalFeature>

org.apache.ambari.annotations.ExperimentalFeature

All Implemented Interfaces:

Serializable, Comparable<ExperimentalFeature>

public enum ExperimentalFeature
extends Enum<ExperimentalFeature>

The ExperimentalFeature enumeration is meant to be used with the Experimental annotation to indicate which feature set experimental code belongs to.

Enum Constant Summary

Enum Constants

Enum Constant and Description
ALERT_CACHING The caching of current alert information in order to reduce overall load on the database by preventing frequent updates and JPA entity invalidation.
CUSTOM_SERVICE_REPOS Support for service-specific repos for custom services
MULTI_SERVICE For code that is for multi-service
ORPHAN_KERBEROS_IDENTITY_REMOVAL Automatically removing Kerberos identities when a service or component is removed.
PATCH_UPGRADES Used for code that is targeted for patch upgrades
REFACTOR_TO_SPI Member should be refactored to SPI project

ALERT_CACHING

public static final ExperimentalFeature ALERT_CACHING

The caching of current alert information in order to reduce overall load on the database by preventing frequent updates and JPA entity invalidation.

PATCH_UPGRADES

public static final ExperimentalFeature PATCH_UPGRADES

Used for code that is targeted for patch upgrades

MULTI_SERVICE

public static final ExperimentalFeature MULTI_SERVICE

For code that is for multi-service

CUSTOM_SERVICE_REPOS

public static final ExperimentalFeature CUSTOM_SERVICE_REPOS

Support for service-specific repos for custom services

ORPHAN_KERBEROS_IDENTITY_REMOVAL

public static final ExperimentalFeature ORPHAN_KERBEROS_IDENTITY_REMOVAL

Automatically removing Kerberos identities when a service or component is removed.

REFACTOR_TO_SPI

public static final ExperimentalFeature REFACTOR_TO_SPI

Method Detail

values

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

Returns:

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

valueOf

public static ExperimentalFeature 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
