public interface ShortCollection
extends Collection<Short>, ShortIterable

A type-specific Collection; provides some additional methods that use polymorphism to avoid (un)boxing.

Additionally, this class defines strengthens (again) iterator().

Collection

Method Summary

Modifier and Type	Method and Description
boolean	add(short key) Ensures that this collection contains the specified element (optional operation).
default boolean	add(Short key) Deprecated. Please use the corresponding type-specific method instead.
boolean	addAll(ShortCollection c) Adds all elements of the given type-specific collection to this collection.
default boolean	contains(Object key) Deprecated. Please use the corresponding type-specific method instead.
boolean	contains(short key) Returns true if this collection contains the specified element.
boolean	containsAll(ShortCollection c) Checks whether this collection contains all elements from the given type-specific collection.
ShortIterator	iterator() Returns a type-specific iterator on the elements of this collection.
boolean	rem(short key) Removes a single instance of the specified element from this collection, if it is present (optional operation).
default boolean	remove(Object key) Deprecated. Please use (and implement) the rem() method instead.
boolean	removeAll(ShortCollection c) Remove from this collection all elements in the given type-specific collection.
default boolean	removeIf(IntPredicate filter) Remove from this collection all elements which satisfy the given predicate.
default boolean	removeIf(Predicate<? super Short> filter) Deprecated. Please use the corresponding type-specific method instead.
boolean	retainAll(ShortCollection c) Retains in this collection only elements from the given type-specific collection.
short[]	toArray(short[] a) Returns an array containing all of the elements in this collection; the runtime type of the returned array is that of the specified array.
short[]	toShortArray() Returns a primitive type array containing the items of this collection.
short[]	toShortArray(short[] a) Deprecated. Please use toArray() instead—this method is redundant and will be removed in the future.

Method Detail

iterator

ShortIterator iterator()

Returns a type-specific iterator on the elements of this collection.

Note that this specification strengthens the one given in Iterable.iterator(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends Collection.

Specified by:

iterator in interface Collection<Short>

Specified by:

iterator in interface Iterable<Short>

Specified by:

iterator in interface ShortIterable

Returns:

a type-specific iterator on the elements of this collection.

See Also:

Iterable.iterator()

add

boolean add(short key)

Ensures that this collection contains the specified element (optional operation).

See Also:

Collection.add(Object)

contains

boolean contains(short key)

Returns true if this collection contains the specified element.

See Also:

Collection.contains(Object)

rem

boolean rem(short key)

Removes a single instance of the specified element from this collection, if it is present (optional operation).

Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

See Also:

Collection.remove(Object)

add

@Deprecated
default boolean add(Short key)

Deprecated. Please use the corresponding type-specific method instead.

Specified by:

add in interface Collection<Short>

contains

@Deprecated
default boolean contains(Object key)

Deprecated. Please use the corresponding type-specific method instead.

Specified by:

contains in interface Collection<Short>

remove

@Deprecated
default boolean remove(Object key)

Deprecated. Please use (and implement) the rem() method instead.

Specified by:

remove in interface Collection<Short>

toShortArray

short[] toShortArray()

Returns a primitive type array containing the items of this collection.

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray()

toShortArray

@Deprecated
short[] toShortArray(short[] a)

Deprecated. Please use toArray() instead—this method is redundant and will be removed in the future.

Returns a primitive type array containing the items of this collection.

Note that, contrarily to Collection.toArray(Object[]), this methods just writes all elements of this collection: no special value will be added after the last one.

Parameters:

a - if this array is big enough, it will be used to store this collection.

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray(Object[])

toArray

short[] toArray(short[] a)

Returns an array containing all of the elements in this collection; the runtime type of the returned array is that of the specified array.

Note that, contrarily to Collection.toArray(Object[]), this methods just writes all elements of this collection: no special value will be added after the last one.

Parameters:

a - if this array is big enough, it will be used to store this collection.

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray(Object[])

addAll

boolean addAll(ShortCollection c)

Adds all elements of the given type-specific collection to this collection.

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

Collection.addAll(Collection)

containsAll

boolean containsAll(ShortCollection c)

Checks whether this collection contains all elements from the given type-specific collection.

Parameters:

c - a type-specific collection.

Returns:

true if this collection contains all elements of the argument.

See Also:

Collection.containsAll(Collection)

removeAll

boolean removeAll(ShortCollection c)

Remove from this collection all elements in the given type-specific collection.

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

Collection.removeAll(Collection)

removeIf

@Deprecated
default boolean removeIf(Predicate<? super Short> filter)

Deprecated. Please use the corresponding type-specific method instead.

Specified by:

removeIf in interface Collection<Short>

removeIf

default boolean removeIf(IntPredicate filter)

Remove from this collection all elements which satisfy the given predicate.

Parameters:

filter - a predicate which returns true for elements to be removed.

Returns:

true if any elements were removed.

See Also:

Collection.removeIf(java.util.function.Predicate)

retainAll

boolean retainAll(ShortCollection c)

Retains in this collection only elements from the given type-specific collection.

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

Collection.retainAll(Collection)
