public abstract class AbstractObjectCollection<K> extends AbstractCollection<K> implements ObjectCollection<K>
An abstract class providing basic methods for collections implementing a type-specific interface.In particular, this class provide
iterator()
,add()
,AbstractCollection.remove(Object)
andAbstractCollection.contains(Object)
methods that just call the type-specific counterpart.

toArray
public Object[] toArray()
- Specified by:
toArray
in interfaceCollection<K>
- Overrides:
toArray
in classAbstractCollection<K>
-
toArray
public <T> T[] toArray(T[] a)
Description copied from interface:ObjectCollection
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 interfaceCollection<K>
- Specified by:
toArray
in interfaceObjectCollection<K>
- Overrides:
toArray
in classAbstractCollection<K>
- 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
public boolean addAll(Collection<? extends K> c)
Adds all elements of the given collection to this collection.- Specified by:
addAll
in interfaceCollection<K>
- Overrides:
addAll
in classAbstractCollection<K>
- Parameters:
c
- a collection.- Returns:
true
if this collection changed as a result of the call.
-
add
public boolean add(K k)
- Specified by:
add
in interfaceCollection<K>
- Overrides:
add
in classAbstractCollection<K>
-
objectIterator
@Deprecated public ObjectIterator<K> objectIterator()
Deprecated.Delegates to the new covariantly stronger generic method.- Specified by:
objectIterator
in interfaceObjectCollection<K>
- See Also:
ObjectCollection.iterator()
-
iterator
public abstract ObjectIterator<K> iterator()
Description copied from interface:ObjectCollection
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 extendsCollection
.- Specified by:
iterator
in interfaceCollection<K>
- Specified by:
iterator
in interfaceIterable<K>
- Specified by:
iterator
in interfaceObjectCollection<K>
- Specified by:
iterator
in interfaceObjectIterable<K>
- Specified by:
iterator
in classAbstractCollection<K>
- Returns:
- a type-specific iterator on the elements of this collection.
-
containsAll
public boolean containsAll(Collection<?> c)
Checks whether this collection contains all elements from the given collection.- Specified by:
containsAll
in interfaceCollection<K>
- Overrides:
containsAll
in classAbstractCollection<K>
- Parameters:
c
- a collection.- Returns:
true
if this collection contains all elements of the argument.
-
retainAll
public boolean retainAll(Collection<?> c)
Retains in this collection only elements from the given collection.- Specified by:
retainAll
in interfaceCollection<K>
- Overrides:
retainAll
in classAbstractCollection<K>
- Parameters:
c
- a collection.- Returns:
true
if this collection changed as a result of the call.
-
removeAll
public boolean removeAll(Collection<?> c)
Remove from this collection all elements in the given collection. If the collection is an instance of this class, it uses faster iterators.- Specified by:
removeAll
in interfaceCollection<K>
- Overrides:
removeAll
in classAbstractCollection<K>
- Parameters:
c
- a collection.- Returns:
true
if this collection changed as a result of the call.

isEmpty
in interfaceCollection<K>
- Overrides:
isEmpty
in classAbstractCollection<K>
-
toString
public String toString()
- Overrides:
