Enclosing class:
ImmutableSortedSet<E>

public static final class ImmutableSortedSet.Builder<E>
extends ImmutableSet.Builder<E>

A builder for creating immutable sorted set instances, especially public static final sets ("constant sets"), with a given comparator. Example:

   public static final ImmutableSortedSet<Number> LUCKY_NUMBERS =
       new ImmutableSortedSet.Builder<Number>(ODDS_FIRST_COMPARATOR)
           .addAll(SINGLE_DIGIT_PRIMES)
           .add(42)
           .build();
Builder instances can be reused; it is safe to call build() multiple times to build multiple sets in series. Each set is a superset of the set created before it.

Constructor Detail

ImmutableSortedSet.Builder

public ImmutableSortedSet.Builder(Comparator<? super E> comparator)
Creates a new builder. The returned builder is equivalent to the builder generated by ImmutableSortedSet.orderedBy(java.util.Comparator).

Method Detail

add

public ImmutableSortedSet.Builder<E> add(E element)
Adds element to the ImmutableSortedSet. If the ImmutableSortedSet already contains element, then add has no effect. (only the previously added element is retained).

Overrides:
add in class ImmutableSet.Builder<E>
Parameters:
element - the element to add
Returns:
this Builder object
Throws:
NullPointerException - if element is null

add

public ImmutableSortedSet.Builder<E> add(E... elements)
Adds each element of elements to the ImmutableSortedSet, ignoring duplicate elements (only the first duplicate element is added).

Overrides:
add in class ImmutableSet.Builder<E>
Parameters:
elements - the elements to add
Returns:
this Builder object
Throws:
NullPointerException - if elements contains a null element

addAll

public ImmutableSortedSet.Builder<E> addAll(Iterable<? extends E> elements)
Adds each element of elements to the ImmutableSortedSet, ignoring duplicate elements (only the first duplicate element is added).

Overrides:
addAll in class ImmutableSet.Builder<E>
Parameters:
elements - the elements to add to the ImmutableSortedSet
Returns:
this Builder object
Throws:
NullPointerException - if elements contains a null element

addAll

public ImmutableSortedSet.Builder<E> addAll(Iterator<? extends E> elements)
Adds each element of elements to the ImmutableSortedSet, ignoring duplicate elements (only the first duplicate element is added).

Overrides:
addAll in class ImmutableSet.Builder<E>
Parameters:
elements - the elements to add to the ImmutableSortedSet
Returns:
this Builder object
Throws:
NullPointerException - if elements contains a null element

build

public ImmutableSortedSet<E> build()
Returns a newly-created ImmutableSortedSet based on the contents of the Builder and its comparator.

Overrides:
build in class ImmutableSet.Builder<E>
