Enum Class RedundancyTier

java.lang.Object

java.lang.Enum<RedundancyTier>

com.eqixiac.equinix.design.optimizer.enums.RedundancyTier

All Implemented Interfaces:

Serializable, Comparable<RedundancyTier>, Constable

public enum RedundancyTier
extends Enum<RedundancyTier>

The least redundancy a design accepts. Each tier is an explicit, checkable rule on the SET of metros a design uses (enforced by the minimum_redundancy constraint); no tier steers selection any other way, and none silently forces a cross-region spread.

• NONE: one metro is enough.
• N_PLUS_1: at least two metros, at least two of them in the same region (a nearby standby that fails over without crossing a region).
• MULTI_METRO: at least two metros, in any regions.
• MULTI_REGION: at least two metros in at least two different regions.

Method Details

values

public static RedundancyTier[] 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 RedundancyTier 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
