forEach

public void forEach(int startIndex,
 int endIndex,
 Procedure<? super T> procedure)

Description copied from interface: OrderedIterable

Iterates over the section of the iterable covered by the specified inclusive indexes. The indexes are both inclusive.

e.g.

people.forEach(0, 1, person -> LOGGER.info(person.getName()));

This code would output ted and mary's names.

Specified by:

each

public void each(Procedure<? super T> procedure)

The procedure is executed for each element in the iterable.

Example using a Java 8 lambda expression:

e.g.
OrderedIterable<People> people = FastList.newListWith(ted, mary, bob, sally)
people.forEachWithIndex(0, 1, (person, index) -> LOGGER.info(person.getName()));

This code would output ted and mary's names.

Specified by:

forEachWith

public <P> void forEachWith(Procedure2<? super T, ? super P> procedure,
 P parameter)

Description copied from interface: InternalIterable

Example using a Java 8 lambda:

people.forEachWith((Person person, Person other) ->
    {

        {
             LOGGER.info(person.getName());
        }
    }, fred);

Example using an anonymous inner class:

people.forEachWith(new Procedure2<Person, Person>()
{
    public void value(Person person, Person other)
    {
        if (person.isRelatedTo(other))

getFirst

public T getFirst()

Description copied from interface: RichIterable

Returns the first element of an iterable. In the case of a List it is the element at the first index. In the case of any other Collection, it is the first element that would be returned during an iteration. If the iterable is empty, null is returned. If null is a valid element of the container, then a developer would need to check to see if the iterable is empty to validate that a null result was not due to the container being empty.

The order of Sets are not guaranteed (except for TreeSets and other Ordered Set implementations), so if you use this method, the first element could be any element from the Set.

getFirst in interface OrderedIterable<T>

getFirst in interface RichIterable<T>

getLast

public T getLast()

Description copied from interface: RichIterable

Returns the last element of an iterable. In the case of a List it is the element at the last index. In the case of any other Collection, it is the last element that would be returned during an iteration. If the iterable is empty, null is returned. If null is a valid element of the container, then a developer would need to check to see if the iterable is empty to validate that a null result was not due to the container being empty.
