Enclosing class:

CharBigListIterators

public abstract static class CharBigListIterators.AbstractIndexBasedBigListIterator
extends CharBigListIterators.AbstractIndexBasedBigIterator
implements it.unimi.dsi.fastutil.chars.CharBigListIterator

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,
                            char k)

Add the given item at the given index.

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

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

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

set

protected abstract void set(long location,
                            char k)

Sets the given item at the given index.

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