Method Detail

unrestricted

public SortedSet<E> unrestricted()

Description copied from class: CollectionsExt.AbstractImmutableCollection

Returns the underlying set without the restrictions imposed by this CollectionsExt.ImmutableCollection. Note that the result may still throw UnsupportedOperationExceptions depending on the implementation.

Specified by:

unrestricted in class CollectionsExt.AbstractImmutableCollection<SortedSet<E>,E>

comparator

public Comparator<? super E> comparator()

Specified by:

comparator in interface SortedSet<E>

first

public E first()

Specified by:

first in interface SortedSet<E>

last

public E last()

Specified by:

last in interface SortedSet<E>

headSet

public SortedSet<E> headSet(E toElement)

Returns a view of the portion of this set whose elements are strictly less than toElement. For information on backing see subSet(Object, Object).

Specified by:

headSet in interface SortedSet<E>

subSet

public SortedSet<E> subSet(E fromElement,
                           E toElement)

Returns a view of the portion of this set whose elements range from fromElement, inclusive, to toElement, exclusive. (If fromElement and toElement are equal, the returned set is empty.) The returned set is backed by this set, so changes in the returned set are reflected in this set, and vice-versa. The returned set supports all optional set operations that this set supports. In particular, changes of the allowed modifications (returned by CollectionsExt.AbstractImmutableCollection.allowedModifications()) of the returned set are reflected in this set, and vice-versa.

Specified by:

subSet in interface SortedSet<E>

tailSet

public SortedSet<E> tailSet(E fromElement)

Returns a view of the portion of this set whose elements are greater than or equal to fromElement. For information on backing see subSet(Object, Object).

Specified by:

tailSet in interface SortedSet<E>
