public class SplitterPartitioner
extends AbstractPartitioner

Implementation of Partitioner that locates multiple resources and associates their file names with execution context keys.

Creates an ExecutionContext per resource, and labels them as {partition0, partition1, ..., partitionN} where 'partition' part comes from a AbstractPartitioner.getPartitionBaseIdentifier().

The grid size information passed to method Partitioner.partition(int) is ignored.
