Enum VoidSerializer

java.lang.Object

java.lang.Enum<VoidSerializer>

org.apache.flink.test.util.source.VoidSerializer

All Implemented Interfaces:

Serializable, Comparable<VoidSerializer>, org.apache.flink.core.io.SimpleVersionedSerializer<Void>, org.apache.flink.core.io.Versioned

public enum VoidSerializer
extends Enum<VoidSerializer>
implements org.apache.flink.core.io.SimpleVersionedSerializer<Void>

A serializer for Void checkpoint states. This is useful for test sources that don't need to store any checkpoint state. The serializer always returns null during deserialization and stores no data during serialization.

Method Detail

values

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

Returns:

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

valueOf

public static VoidSerializer 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
