Method Details

size

public int size()

Description copied from interface: RichIterable

Returns the number of items in this iterable.

Specified by:

size in interface Collection<T>

Specified by:

size in interface RichIterable<T>

Specified by:

size in interface Set<T>

equals

public boolean equals(Object o)

Description copied from interface: SetIterable

Follows the same general contract as Set.equals(Object).

Specified by:

equals in interface Collection<T>

Specified by:

equals in interface Set<T>

Specified by:

equals in interface SetIterable<T>

Overrides:

equals in class Object

hashCode

public int hashCode()

Description copied from interface: SetIterable

Follows the same general contract as Set.hashCode().

Specified by:

hashCode in interface Collection<T>

Specified by:

hashCode in interface Set<T>

Specified by:

hashCode in interface SetIterable<T>

Overrides:

hashCode in class Object

newWith

public ImmutableSet<T> newWith(T element)

Description copied from interface: ImmutableCollection

This method is similar to the with method in MutableCollection with the difference that a new copy of this collection with the element appended will be returned.

Specified by:

newWith in interface ImmutableCollection<T>

Specified by:

newWith in interface ImmutableSet<T>

Overrides:

newWith in class AbstractImmutableSet<T>

newWithout

public ImmutableSet<T> newWithout(T element)

Description copied from interface: ImmutableCollection

This method is similar to the without method in MutableCollection with the difference that a new copy of this collection with the element removed will be returned.

Specified by:

newWithout in interface ImmutableCollection<T>

Specified by:

newWithout in interface ImmutableSet<T>

Overrides:

newWithout in class AbstractImmutableSet<T>

contains

public boolean contains(Object obj)

Description copied from interface: RichIterable

Returns true if the iterable has an element which responds true to element.equals(object).

Specified by:

contains in interface Collection<T>

Specified by:

contains in interface RichIterable<T>

Specified by:

contains in interface Set<T>

Overrides:

contains in class AbstractRichIterable<T>

iterator

public Iterator<T> iterator()

Specified by:

iterator in interface Collection<T>

Specified by:

iterator in interface Iterable<T>

Specified by:

iterator in interface Set<T>

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.

Specified by:

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.

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

Specified by:

getLast in interface RichIterable<T>

getOnly

public T getOnly()

Description copied from interface: RichIterable

Returns the element if the iterable has exactly one element. Otherwise, throw IllegalStateException.

Specified by:

getOnly in interface RichIterable<T>

Returns:

an element of an iterable.

each

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

Description copied from interface: RichIterable

The procedure is executed for each element in the iterable.

Example using a Java 8 lambda expression:

people.each(person -> LOGGER.info(person.getName()));

This method is a variant of InternalIterable.forEach(Procedure) that has a signature conflict with Iterable.forEach(java.util.function.Consumer).

Specified by:

each in interface RichIterable<T>

See Also:

• InternalIterable.forEach(Procedure)
• Iterable.forEach(java.util.function.Consumer)

forEachWithIndex

public void forEachWithIndex(ObjectIntProcedure<? super T> objectIntProcedure)

Description copied from interface: InternalIterable

Iterates over the iterable passing each element and the current relative int index to the specified instance of ObjectIntProcedure.

Example using a Java 8 lambda:

people.forEachWithIndex((Person person, int index) -> LOGGER.info("Index: " + index + " person: " + person.getName()));

Example using an anonymous inner class:

people.forEachWithIndex(new ObjectIntProcedure<Person>()
{
    public void value(Person person, int index)
    {
        LOGGER.info("Index: " + index + " person: " + person.getName());
    }
});

Specified by:

forEachWithIndex in interface InternalIterable<T>

Overrides:

forEachWithIndex in class AbstractRichIterable<T>

forEachWith

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

Description copied from interface: InternalIterable

The procedure2 is evaluated for each element in the iterable with the specified parameter provided as the second argument.

Example using a Java 8 lambda:

people.forEachWith((Person person, Person other) ->
    {
        if (person.isRelatedTo(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))
        {
             LOGGER.info(person.getName());
        }
    }
}, fred);

Specified by:

forEachWith in interface InternalIterable<T>

Overrides:

forEachWith in class AbstractRichIterable<T>
