Enclosing class:

ObjectBigListIterators

public abstract static class ObjectBigListIterators.AbstractIndexBasedBigListIterator<K>
extends ObjectBigListIterators.AbstractIndexBasedBigIterator<K>
implements it.unimi.dsi.fastutil.objects.ObjectBigListIterator<K>

A skeletal implementation for a list-iterator backed by an index based data store. High performance concrete implementations (like the main ListIterator of ArrayList) 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).

Constructor Detail

AbstractIndexBasedBigListIterator

protected AbstractIndexBasedBigListIterator(long minPos,
                                            long initialPos)

Method Detail

add

protected abstract void add(long location,
                            K k)

Add the given item at the given index.

This method should also do what is needed to track the change to the ObjectBigListIterators.AbstractIndexBasedBigIterator.getMaxPos(). Usually this is accomplished by having this method call the parent Collection's appropriate add method, and having ObjectBigListIterators.AbstractIndexBasedBigIterator.getMaxPos() track the parent collection's size.

Do not modify ObjectBigListIterators.AbstractIndexBasedBigIterator.pos in this method; the default #add() method takes care of this.

See ObjectBigListIterators.AbstractIndexBasedBigIterator.pos and #get(int) for discussion on what the location means.

set

protected abstract void set(long location,
                            K k)

Sets the given item at the given index.

See ObjectBigListIterators.AbstractIndexBasedBigIterator.pos and #get(int) for discussion on what the location means.
