Class SparseArrayIndexedIterator<E>

java.lang.Object

org.apache.jena.util.iterator.NiceIterator<FastHashSet.IndexedKey<E>>

org.apache.jena.mem2.iterator.SparseArrayIndexedIterator<E>

Type Parameters:

E - the type of the array elements

All Implemented Interfaces:

Iterator<FastHashSet.IndexedKey<E>>, org.apache.jena.atlas.iterator.IteratorCloseable<FastHashSet.IndexedKey<E>>, org.apache.jena.atlas.lib.Closeable, ClosableIterator<FastHashSet.IndexedKey<E>>, ExtendedIterator<FastHashSet.IndexedKey<E>>

public class SparseArrayIndexedIterator<E>
extends NiceIterator<FastHashSet.IndexedKey<E>>
implements Iterator<FastHashSet.IndexedKey<E>>

An iterator over a sparse array, that skips null entries. This iterator returns elements as FastHashSet.IndexedKey objects, which contain both the index and the value of the element. The iterator works in ascending order, starting from index 0 up to the specified exclusive index. This iterator will check for concurrent modifications by invoking a Runnable

Method Details

hasNext

public boolean hasNext()

Returns true if the iteration has more elements. (In other words, returns true if next() would return an element rather than throwing an exception.)

Specified by:

hasNext in interface Iterator<E>

Overrides:

hasNext in class NiceIterator<FastHashSet.IndexedKey<E>>

Returns:

true if the iteration has more elements

next

public FastHashSet.IndexedKey<E> next()

Returns the next element in the iteration.

Specified by:

next in interface Iterator<E>

Overrides:

next in class NiceIterator<FastHashSet.IndexedKey<E>>

Returns:

the next element in the iteration

Throws:

NoSuchElementException - if the iteration has no more elements

forEachRemaining

public void forEachRemaining(Consumer<? super FastHashSet.IndexedKey<E>> action)

Specified by:

forEachRemaining in interface Iterator<E>
