java.lang.Object

it.unimi.dsi.fastutil.doubles.AbstractDoubleIterator

it.unimi.dsi.fastutil.doubles.DoubleBigListIterators.AbstractIndexBasedBigIterator

All Implemented Interfaces:

DoubleIterator, Iterator<Double>, PrimitiveIterator<Double,DoubleConsumer>, PrimitiveIterator.OfDouble

Direct Known Subclasses:

DoubleBigListIterators.AbstractIndexBasedBigListIterator

Enclosing class:

DoubleBigListIterators

public abstract static class DoubleBigListIterators.AbstractIndexBasedBigIterator
extends AbstractDoubleIterator

A skeletal implementation for an iterator backed by an index based data store. High performance concrete implementations (like the main Iterator of BigArrayBigList) generally should avoid using this and just implement the interface directly, but should be decent for less performance critical implementations.

As the abstract methods in this class are used in inner loops, it is generally a good idea to override the class as final as to encourage the JVM to inline them (or alternatively, override the abstract methods as final).

Method Details

hasNext

public boolean hasNext()

nextDouble

public double nextDouble()

Description copied from interface: DoubleIterator

Returns the next element as a primitive type.

Returns:

the next element in the iteration.

See Also:

• Iterator.next()

remove

public void remove()

forEachRemaining

public void forEachRemaining(DoubleConsumer action)

skip

public long skip(long n)

skip

public int skip(int n)

Description copied from interface: DoubleIterator

Skips the given number of elements.

The effect of this call is exactly the same as that of calling DoubleIterator.next() for n times (possibly stopping if Iterator.hasNext() becomes false).

Parameters:

n - the number of elements to skip.

Returns:

the number of elements actually skipped.

• Iterator.next()
