getBatches

public static List<JobBatch> getBatches(int totalJobs,
                                        int chunks)

Provides a List of indices based on the desired split size.

Parameters:

totalJobs - The size of the source List being split

chunks - The range (i.e. to - from) of each batch. The last batch may be smaller than this but the other batches are guaranteed to be of this size.

Returns:

A Serializable List of indexes with totalJobs/batches increments.

splitToList

public <T> List<T> splitToList(T[] arr)

split

public <T> T[] split(T[] arr)

split

public <T> List<T> split(List<T> list)

Splits the given list based on this class's indices.

Type Parameters:

T - The type of the List

Parameters:

list - The list to call List.subList(int, int) on

Returns:

The split list.
