java.lang.Enum<Repartition>

org.deeplearning4j.spark.api.Repartition

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Repartition>

public enum Repartition
extends java.lang.Enum<Repartition>

Enumeration that is used for specifying the behaviour of repartitioning in ParameterAveragingTrainingMaster (and possibly elsewhere. "Never" and "Always" repartition options are as expected; the "NumPartitionsWorkersDiffers" will repartition data if and only if the number of partitions is not equal to the number of workers (total cores). Note however that even if the number of partitions and number of workers differ, this does not guarantee that those partitions are balanced (in terms of number of elements) in any way.

Method Detail

values

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

Returns:

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

valueOf

public static Repartition valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
