Enum Class ExponentialHistogramBlock.Component

java.lang.Object

java.lang.Enum<ExponentialHistogramBlock.Component>

org.elasticsearch.compute.data.ExponentialHistogramBlock.Component

All Implemented Interfaces:

Serializable, Comparable<ExponentialHistogramBlock.Component>, Constable

Enclosing interface:

ExponentialHistogramBlock

public static enum ExponentialHistogramBlock.Component
extends Enum<ExponentialHistogramBlock.Component>

Exponential histograms are composite data types. This enum defines the components that can be directly accessed, potentially avoiding loading the entire histogram from disk.
This enum can be safely serialized via StreamOutput.writeEnum(Enum).

Enum Constant Summary

Enum Constants

Enum Constant	Description
COUNT	The number of all values summarized by the histogram, 0 if the histogram is empty.

Method Details

values

public static ExponentialHistogramBlock.Component[] 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 ExponentialHistogramBlock.Component 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
