Class AbstractFloatCollection
- All Implemented Interfaces:
FloatCollection
,FloatIterable
,Iterable<Float>
,Collection<Float>
- Direct Known Subclasses:
AbstractFloatBigList
,AbstractFloatList
,AbstractFloatSet
,FloatCollections.EmptyCollection
,FloatCollections.IterableCollection
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.

iterator
Description copied from interface:FloatCollection
Returns a type-specific iterator on the elements of this collection.- Specified by:
iterator
in interfaceCollection<Float>
- Specified by:
iterator
in interfaceFloatCollection
- Specified by:
iterator
in interfaceFloatIterable
- Specified by:
iterator
in interfaceIterable<Float>
- Specified by:
iterator
in classAbstractCollection<Float>
- Returns:
- a type-specific iterator on the elements of this collection.
- See Also:
-
add
public boolean add(float k) Ensures that this collection contains the specified element (optional operation).- Specified by:
add
in interfaceFloatCollection
- See Also:
- Implementation Specification:
- This implementation always throws an
UnsupportedOperationException
.
-
contains
public boolean contains(float k) Returnstrue
if this collection contains the specified element.- Specified by:
contains
in interfaceFloatCollection
- See Also:
- Implementation Specification:
- This implementation iterates over the elements in the collection, looking for the specified element.
-
rem
public boolean rem(float 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 theList
interface forces us to use a distinguished name. For simplicity, the set interfaces reinstatesremove()
.- Specified by:
rem
in interfaceFloatCollection
- See Also:
- Implementation Specification:
- This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it.

toArray
public float[] toArray(float[] a) Description copied from interface:FloatCollection
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

toArray
in interfaceFloatCollection
- 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:

Returns a primitive type array containing the items of this collection.- Specified by:
toFloatArray
in interfaceFloatCollection
- Returns:
- a primitive type array containing the items of this collection.
