Class AbstractShortCollection

java.lang.Object

java.util.AbstractCollection<java.lang.Short>

it.unimi.dsi.fastutil.shorts.AbstractShortCollection

All Implemented Interfaces:

ShortCollection, ShortIterable, java.lang.Iterable<java.lang.Short>, java.util.Collection<java.lang.Short>

Direct Known Subclasses:

AbstractShortList, ShortCollections.EmptyCollection, ShortCollections.IterableCollection

public abstract class AbstractShortCollection
extends java.util.AbstractCollection<java.lang.Short>
implements ShortCollection

An abstract class providing basic methods for collections implementing a type-specific interface.

In particular, this class provide iterator(), add(), remove(Object) and contains(Object) methods that just call the type-specific counterpart.

Warning: Because of a name clash between the list and collection interfaces the type-specific deletion method of a type-specific abstract collection is rem(), rather then remove(). A subclass must thus override rem(), rather than remove(), to make all inherited methods work properly.

Modifier and Type	Method and Description
boolean	add(short k) Ensures that this collection contains the specified element (optional operation).

boolean	addAll(java.util.Collection<? extends java.lang.Short> c)
boolean	addAll(ShortCollection c) Adds all elements of the given type-specific collection to this collection.
boolean	contains(java.lang.Object key) Deprecated. Please use the corresponding type-specific method instead.
boolean	contains(short k) Returns true if this collection contains the specified element.
boolean	containsAll(java.util.Collection<?> c)
boolean	containsAll(ShortCollection c) Checks whether this collection contains all elements from the given type-specific collection.
abstract it.unimi.dsi.fastutil.shorts.ShortIterator	iterator() Returns a type-specific iterator on the elements of this collection.
boolean	rem(short k) Removes a single instance of the specified element from this collection, if it is present (optional operation).
boolean	remove(java.lang.Object key) Deprecated. Please use the corresponding type-specific method instead.
boolean	removeAll(java.util.Collection<?> c)
boolean	removeAll(ShortCollection c) Remove from this collection all elements in the given type-specific collection.
boolean	retainAll(java.util.Collection<?> c)
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

public abstract it.unimi.dsi.fastutil.shorts.ShortIterator iterator()

Description copied from interface: ShortCollection

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

Specified by:

iterator in interface ShortCollection

Specified by:

iterator in interface ShortIterable

Specified by:

iterator in interface java.lang.Iterable<java.lang.Short>

Specified by:

iterator in interface java.util.Collection<java.lang.Short>

Specified by:

iterator in class java.util.AbstractCollection<java.lang.Short>

Returns:

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

See Also:

Iterable.iterator()

add

public boolean add(short k)

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

Specified by:

add in interface ShortCollection

See Also:

Collection.add(Object)

contains

public boolean contains(short k)

Returns true if this collection contains the specified element.

Specified by:

contains in interface ShortCollection

See Also:

Collection.contains(Object)

rem

public boolean rem(short k)

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().

Specified by:

rem in interface ShortCollection

See Also:

Collection.remove(Object)

add

@Deprecated
public boolean add(java.lang.Short key)

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

Specified by:

add in interface ShortCollection

Specified by:

add in interface java.util.Collection<java.lang.Short>

Overrides:

add in class java.util.AbstractCollection<java.lang.Short>

contains

@Deprecated
public boolean contains(java.lang.Object key)

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

Specified by:

contains in interface ShortCollection

Specified by:

contains in interface java.util.Collection<java.lang.Short>

Overrides:

contains in class java.util.AbstractCollection<java.lang.Short>

remove

@Deprecated
public boolean remove(java.lang.Object key)

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

Specified by:

remove in interface ShortCollection

Specified by:

remove in interface java.util.Collection<java.lang.Short>

Overrides:

remove in class java.util.AbstractCollection<java.lang.Short>

toArray

public short[] toArray(short[] a)

Description copied from interface: ShortCollection

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.

Specified by:

toArray in interface ShortCollection

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[])

toShortArray

public short[] toShortArray()

Description copied from interface: ShortCollection

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

Specified by:

toShortArray in interface ShortCollection

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray()

toShortArray

@Deprecated
public 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.

Specified by:

toShortArray in interface ShortCollection

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[])
