Class SparseArrayIndexedSpliterator<E>

java.lang.Object

org.apache.jena.mem.spliterator.SparseArrayIndexedSpliterator<E>

Type Parameters:

E - the type of the array elements

All Implemented Interfaces:

Spliterator<FastHashSet.IndexedKey<E>>

public class SparseArrayIndexedSpliterator<E>
extends Object
implements Spliterator<FastHashSet.IndexedKey<E>>

A spliterator for sparse arrays. This spliterator will iterate over the array skipping null entries. This spliterator returns elements as FastHashSet.IndexedKey objects, which contain both the index and the value of the element.

This spliterator works in ascending order, starting from the given start up to the specified exclusive index.

This spliterator supports splitting into sub-spliterators.

The spliterator will check for concurrent modifications by invoking a Runnable before each action.
