Enum Condition.CacheLevel

java.lang.Object

java.lang.Enum<Condition.CacheLevel>

com.cloudera.gertrude.Condition.CacheLevel

All Implemented Interfaces:

Serializable, Comparable<Condition.CacheLevel>

Enclosing interface:

Condition<S extends ExperimentState>

public static enum Condition.CacheLevel
extends Enum<Condition.CacheLevel>

An indicator for how often the value of a Condition will change when the Condition.evaluate(ExperimentState) method is called repeatedly.

Enum Constant Summary

Enum Constants

Enum Constant and Description
NONE Indicates that the result of a call to Condition.evaluate(ExperimentState) may never be cached because the result is allowed to change during the lifetime of a single request.
RELOAD Indicates that the result of a call to Condition.evaluate(ExperimentState) will not change at all for the current ExperimentSpace configuration, independent of the value of the ExperimentState argument.
REQUEST Indicates that the result of a call to Condition.evaluate(ExperimentState) will not change when the same ExperimentState instance is passed to the Condition multiple times.

Enum Constant Detail

NONE

public static final Condition.CacheLevel NONE

Indicates that the result of a call to Condition.evaluate(ExperimentState) may never be cached because the result is allowed to change during the lifetime of a single request.

REQUEST

public static final Condition.CacheLevel REQUEST

Indicates that the result of a call to Condition.evaluate(ExperimentState) will not change when the same ExperimentState instance is passed to the Condition multiple times.

RELOAD

public static final Condition.CacheLevel RELOAD

Indicates that the result of a call to Condition.evaluate(ExperimentState) will not change at all for the current ExperimentSpace configuration, independent of the value of the ExperimentState argument.

Method Detail

values

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

Returns:

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

valueOf

public static Condition.CacheLevel 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

merge

public abstract Condition.CacheLevel merge(Condition.CacheLevel other)
