public class PartialListing<T extends FileStatus>
extends Object

A partial listing of the children of a parent directory. Since it is a partial listing, multiple PartialListing may need to be combined to obtain the full listing of a parent directory.

ListingBatch behaves similar to a Future, in that getting the result via get() will throw an Exception if there was a failure.
