public abstract class AbstractShortCollection

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.

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

public short[] toShortArray(short[] a)

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:

addAll

public boolean addAll(ShortCollection c)
Adds all elements of the given type-specific collection to this collection.

Specified by:
addAll in interface ShortCollection
Parameters:
c - a type-specific collection.
Returns:
true if this collection changed as a result of the call.
See Also:
Collection.addAll(Collection)

containsAll

public boolean containsAll(ShortCollection c)
Checks whether this collection contains all elements from the given type-specific collection.

Specified by:
containsAll in interface ShortCollection
Parameters:
c - a type-specific collection.
Returns:
true if this collection contains all elements of the argument.
See Also:
Collection.containsAll(Collection)

retainAll

public boolean retainAll(ShortCollection c)
Retains in this collection only elements from the given type-specific collection.

Specified by:
retainAll in interface ShortCollection
Parameters:
c - a type-specific collection.
Returns:
true if this collection changed as a result of the call.
See Also:
Collection.retainAll(Collection)

removeAll

public boolean removeAll(ShortCollection c)
Remove from this collection all elements in the given type-specific collection.

Specified by:
removeAll in interface ShortCollection
Parameters:
c - a type-specific collection.
Returns:
true if this collection changed as a result of the call.
See Also:

Description copied from interface: ShortCollection
Returns an containing the items of this collection; the runtime type of the returned array is that of the specified array.

Warning: 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
Specified by:
toArray in interface Collection<Short>
Overrides:
toArray in class AbstractCollection<Short>
Parameters:
a - if this array is big enough, it will be used to store this collection.

addAll

public boolean addAll(Collection<? extends Short> c)
Adds all elements of the given collection to this collection.

Specified by:

shortIterator

@Deprecated
public ShortIterator shortIterator()
Deprecated. 

Delegates to the new covariantly stronger generic method.

Specified by:
shortIterator in interface ShortCollection
See Also:
ShortCollection.iterator()

iterator

public abstract ShortIterator iterator()
Description copied from interface: ShortCollection
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 ShortCollection
Specified by:
iterator in interface ShortIterable
Specified by:
iterator in interface Iterable<Short>
Specified by:
iterator in interface Collection<Short>
Specified by:
iterator in class AbstractCollection<Short>
Returns:
a type-specific iterator on the elements of this collection.

remove

public boolean remove(Object ok)
Delegates to the type-specific rem() method.

Specified by:
remove in interface Collection<Short>
Overrides:
remove in class AbstractCollection<Short>

add

public boolean add(Short o)
Delegates to the corresponding type-specific method.

Specified by:
add in interface Collection<Short>
Overrides:
add in class AbstractCollection<Short>

rem

public boolean rem(Object o)
Delegates to the corresponding type-specific method.


contains

public boolean contains(Object o)
Delegates to the corresponding type-specific method.

Specified by:
contains in interface Collection<Short>
Overrides:
contains in class AbstractCollection<Short>

contains

public boolean contains(short k)
Specified by:
contains in interface ShortCollection
See Also:
Collection.contains(Object)

rem

public boolean rem(short k)
Description copied from interface: ShortCollection
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)

Overrides:
retainAll in class AbstractCollection<Short>
Parameters:
c - a collection.
Returns:
true if this collection changed as a result of the call.

removeAll
