Enum Class VeniceHelixToState

java.lang.Object

java.lang.Enum<VeniceHelixToState>

com.linkedin.venice.stats.dimensions.VeniceHelixToState

All Implemented Interfaces:

VeniceDimensionInterface, Serializable, Comparable<VeniceHelixToState>, Constable

public enum VeniceHelixToState
extends Enum<VeniceHelixToState>
implements VeniceDimensionInterface

Helix "to" state for partition state transition metrics. Same values as VeniceHelixFromState but maps to a different dimension key (VeniceMetricsDimensions.VENICE_HELIX_TO_STATE). Values are a subset of HelixState constants, excluding UNKNOWN.

Method Details

values

public static VeniceHelixToState[] 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 VeniceHelixToState 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

getDimensionName

public VeniceMetricsDimensions getDimensionName()

Description copied from interface: VeniceDimensionInterface

Dimension name: Returns the VeniceMetricsDimensions for the enum. All the instances of a Enum class should have the same dimension name. Ideally this could have been a static variable/method in the Enum class, but to enforce having this method via this interface, it is made as a non-static method.

Specified by:

getDimensionName in interface VeniceDimensionInterface
