java.lang.Enum<CompressionKind>

org.apache.orc.CompressionKind

All Implemented Interfaces:

Serializable, Comparable<CompressionKind>

public enum CompressionKind
extends Enum<CompressionKind>

An enumeration that lists the generic compression algorithms that can be applied to ORC files.

NOTE: The file was copied and modified to support zstd-jni. This feature is only supported in ORC 2.0, but 2.0 only supports JDK17. We need to support JDK8.

Method Detail

values

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

Returns:

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

valueOf

public static CompressionKind 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
