Interface SortedSet<E>

All Superinterfaces:

Iterable<E>, Iterable<E>, Set<E>, Traversable<E>

All Known Implementing Classes:

AbstractSortedSet, TreeSet

public interface SortedSet<E>
extends Set<E>

SortedSet defines the interface for sets that are sorted.

Method Summary

Modifier and Type	Method	Description
@NotNull SortedSet<E>	add(E value)	Returns a set that adds the specified value if it doesn't already exist in this set.
SortedSet<E>	asSortedSet()	Returns an immutable view of this set as an instance of java.util.SortedSet.
Comparator<? super E>	comparator()	Returns the comparator associated with this map, or null if the default ordering is used.
@NotNull SortedSet<E>	drop(int number)	Returns a set containing all elements in this set, excluding the first number of elements.
E	first()	Returns the first element in the set or null of the set is empty.
@NotNull SortedSet<E>	from(E value, boolean inclusive)	Returns the bottom of the set starting from the key specified.
E	last()	Returns the last element in the set or null of the set is empty.
@NotNull SortedSet<E>	range(E from, boolean fromInclusive, E to, boolean toInclusive)	Returns a subset of the set between the from and to keys specified.
@NotNull SortedSet<E>	remove(E value)	Removes the specified value from the set if it exists.
@NotNull SortedSet<E>	take(int number)	Returns a set containing the first number of elements from this set.
@NotNull SortedSet<E>	to(E value, boolean inclusive)	Returns the top of the set up until the key specified.

Method Details

first

@Nullable
E first()

Returns the first element in the set or null of the set is empty.

last

@Nullable
E last()

Returns the last element in the set or null of the set is empty.

drop

@NotNull
@NotNull SortedSet<E> drop(int number)

Returns a set containing all elements in this set, excluding the first number of elements.

take

@NotNull
@NotNull SortedSet<E> take(int number)

Returns a set containing the first number of elements from this set.

add

@NotNull
@NotNull SortedSet<E> add(E value)

Description copied from interface: Set

Returns a set that adds the specified value if it doesn't already exist in this set.

Specified by:

add in interface Set<E>

remove

@NotNull
@NotNull SortedSet<E> remove(E value)

Description copied from interface: Set

Removes the specified value from the set if it exists.

Specified by:

remove in interface Set<E>

comparator

Comparator<? super E> comparator()

Returns the comparator associated with this map, or null if the default ordering is used.

from

@NotNull
@NotNull SortedSet<E> from(@NotNull
 E value,
 boolean inclusive)

Returns the bottom of the set starting from the key specified.

Parameters:

inclusive - if true, the key will be included in the result, otherwise it will be excluded

to

@NotNull
@NotNull SortedSet<E> to(@NotNull
 E value,
 boolean inclusive)

Returns the top of the set up until the key specified.

Parameters:

inclusive - if true, the key will be included in the result, otherwise it will be excluded

range

@NotNull
@NotNull SortedSet<E> range(@NotNull
 E from,
 boolean fromInclusive,
 @NotNull
 E to,
 boolean toInclusive)

Returns a subset of the set between the from and to keys specified.

Parameters:

fromInclusive - if true, the key will be included in the result, otherwise it will be excluded

toInclusive - if true, the key will be included in the result, otherwise it will be excluded

asSortedSet

@NotNull
SortedSet<E> asSortedSet()

Returns an immutable view of this set as an instance of java.util.SortedSet.
