Method Detail

headSet

public ContiguousSet<C> headSet(C toElement)

Description copied from class: ImmutableSortedSet

This method returns a serializable ImmutableSortedSet.

The SortedSet.headSet(E) documentation states that a subset of a subset throws an IllegalArgumentException if passed a toElement greater than an earlier toElement. However, this method doesn't throw an exception in that situation, but instead keeps the original toElement.

subSet

public ContiguousSet<C> subSet(C fromElement,
                               C toElement)

Description copied from class: ImmutableSortedSet

This method returns a serializable ImmutableSortedSet.

The SortedSet.subSet(E, E) documentation states that a subset of a subset throws an IllegalArgumentException if passed a fromElement smaller than an earlier fromElement. However, this method doesn't throw an exception in that situation, but instead keeps the original fromElement. Similarly, this method keeps the original toElement, instead of throwing an exception, if passed a toElement greater than an earlier toElement.

tailSet

public ContiguousSet<C> tailSet(C fromElement)

Description copied from class: ImmutableSortedSet

This method returns a serializable ImmutableSortedSet.

intersection

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

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, java.util.Set) for ContiguousSet instances.

range

public abstract Range<C> range()

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).

Throws:

NoSuchElementException - if this set is empty

range

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

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..∞).

Throws:

NoSuchElementException - if this set is empty

toString

public String toString()

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

Overrides:

toString in class ImmutableCollection<C extends Comparable>

builder

@Deprecated
public static <E> ImmutableSortedSet.Builder<E> builder()

Deprecated. Use ImmutableSortedSet.naturalOrder(), which offers better type-safety.

Not supported. Use ImmutableSortedSet.naturalOrder(), which offers better type-safety, instead. This method exists only to hide ImmutableSet.builder() from consumers of ImmutableSortedSet.

Throws:

UnsupportedOperationException - always
