Method Detail

first

public C first()

Specified by:

first in interface java.util.SortedSet<C extends java.lang.Comparable>

Overrides:

first in class ImmutableSortedSet<C extends java.lang.Comparable>

last

public C last()

Specified by:

last in interface java.util.SortedSet<C extends java.lang.Comparable>

Overrides:

last in class ImmutableSortedSet<C extends java.lang.Comparable>

size

public int size()

Specified by:

size in interface java.util.Collection<C extends java.lang.Comparable>

Specified by:

size in interface java.util.Set<C extends java.lang.Comparable>

Specified by:

size in class java.util.AbstractCollection<C extends java.lang.Comparable>

intersection

public ContiguousSet<C> intersection(ContiguousSet<C> other)

Description copied from class: ContiguousSet

Returns the set of values that are contained in both this set and the other.

This method should always be used instead of Sets.intersection(java.util.Set<E>, java.util.Set<?>) for ContiguousSet instances.

Specified by:

intersection in class ContiguousSet<C extends java.lang.Comparable>

range

public Range<C> range()

Description copied from class: ContiguousSet

Returns a range, closed on both ends, whose endpoints are the minimum and maximum values contained in this set. This is equivalent to range(CLOSED, CLOSED).

Specified by:

range in class ContiguousSet<C extends java.lang.Comparable>

range

public Range<C> range(BoundType lowerBoundType,
                      BoundType upperBoundType)

Description copied from class: ContiguousSet

Returns the minimal range with the given boundary types for which all values in this set are contained within the range.

Note that this method will return ranges with unbounded endpoints if BoundType.OPEN is requested for a domain minimum or maximum. For example, if set was created from the range [1..Integer.MAX_VALUE] then set.range(CLOSED, OPEN) must return [1..∞).

Specified by:

range in class ContiguousSet<C extends java.lang.Comparable>

headSetImpl

ContiguousSet<C> headSetImpl(C toElement,
                             boolean inclusive)

Specified by:

headSetImpl in class ContiguousSet<C extends java.lang.Comparable>

subSetImpl

ContiguousSet<C> subSetImpl(C fromElement,
                            boolean fromInclusive,
                            C toElement,
                            boolean toInclusive)

Specified by:

subSetImpl in class ContiguousSet<C extends java.lang.Comparable>

tailSetImpl

ContiguousSet<C> tailSetImpl(C fromElement,
                             boolean fromInclusive)

Specified by:

tailSetImpl in class ContiguousSet<C extends java.lang.Comparable>

contains

public boolean contains(java.lang.Object object)

Specified by:

contains in interface java.util.Collection<C extends java.lang.Comparable>

Specified by:

contains in interface java.util.Set<C extends java.lang.Comparable>

Specified by:

contains in class ImmutableCollection<C extends java.lang.Comparable>

indexOf

@GwtIncompatible
int indexOf(java.lang.Object target)

Description copied from class: ImmutableSortedSet

Returns the position of an element within the set, or -1 if not present.

Specified by:

indexOf in class ImmutableSortedSet<C extends java.lang.Comparable>

iterator

public UnmodifiableIterator<C> iterator()

Description copied from class: ImmutableCollection

Returns an unmodifiable iterator across the elements in this collection.

Specified by:

iterator in interface java.util.Collection<C extends java.lang.Comparable>

Specified by:

iterator in interface java.lang.Iterable<C extends java.lang.Comparable>

Specified by:

Specified by:

descendingIterator in interface java.util.NavigableSet<C extends java.lang.Comparable>

Specified by:

descendingIterator in class ImmutableSortedSet<C extends java.lang.Comparable>

isPartialView

boolean isPartialView()

Description copied from class: ImmutableCollection

Returns true if this immutable collection's implementation contains references to user-created objects that aren't accessible via this collection's methods. This is generally used to determine whether copyOf implementations should make an explicit copy to avoid memory leaks.

Specified by:

isPartialView in class ImmutableCollection<C extends java.lang.Comparable>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface java.util.Collection<C extends java.lang.Comparable>

Specified by:

isEmpty in interface java.util.Set<C extends java.lang.Comparable>

Overrides:

isEmpty in class java.util.AbstractCollection<C extends java.lang.Comparable>

asList

public ImmutableList<C> asList()

Description copied from class: ImmutableCollection

Returns an ImmutableList containing the same elements, in the same order, as this collection.

Performance note: in most cases this method can return quickly without actually copying anything. The exact circumstances under which the copy is performed are undefined and subject to change.

Overrides:

asList in class ImmutableSet<C extends java.lang.Comparable>

toString

public java.lang.String toString()

Description copied from class: ContiguousSet

Returns a short-hand representation of the contents such as "[1..100]".
