Method Details

ceiling

public @Nullable E ceiling(E e)

Description copied from interface: ReadOnlyNavigableSet

Returns the least element in this set greater than or equal to the given element, or null if there is no such element.

Specified by:

ceiling in interface ReadOnlyNavigableSet<E>

Parameters:

e - the given element

Returns:

ceiling element or null

comparator

public @Nullable Comparator<? super E> comparator()

Description copied from interface: ReadOnlySortedSet

Returns the comparator used to order the elements in this set, or null if this set uses the natural ordering of its elements.

Specified by:

comparator in interface ReadOnlySortedSet<E>

Returns:

comparator or null

floor

public @Nullable E floor(E e)

Description copied from interface: ReadOnlyNavigableSet

Returns the greatest element in this set less than or equal to the given element, or null if there is no such element.

Specified by:

floor in interface ReadOnlyNavigableSet<E>

Parameters:

e - the given element

Returns:

floor element or null

higher

public @Nullable E higher(E e)

Description copied from interface: ReadOnlyNavigableSet

Returns the least element in this set greater than the given element, or null if there is no such element.

Specified by:

higher in interface ReadOnlyNavigableSet<E>

Parameters:

lower

public @Nullable E lower(E e)

Description copied from interface: ReadOnlyNavigableSet
