Method Detail

iterator
FloatIterator 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 extendsCollection
.- Specified by:
iterator
in interfaceCollection<Float>
- Specified by:
iterator
in interfaceFloatIterable
- Specified by:
iterator
in interfaceIterable<Float>
- Returns:
- a type-specific iterator on the elements of this collection.
- See Also:
Iterable.iterator()
-
add
boolean add(float key)
Ensures that this collection contains the specified element (optional operation).- See Also:
Collection.add(Object)
-
contains
boolean contains(float key)
Returnstrue
if this collection contains the specified element.- See Also:
Collection.contains(Object)
-
rem
boolean rem(float 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 theList
interface forces us to use a distinguished name. For simplicity, the set interfaces reinstatesremove()
.- See Also:
Collection.remove(Object)

Deprecated.Please use the corresponding type-specific method instead.- Specified by:

remove
@Deprecated default boolean remove(Object key)
Deprecated.Please use (and implement) therem()
method instead.- Specified by:

toFloatArray
float[] toFloatArray()
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()
-
toFloatArray
@Deprecated float[] toFloatArray(float[] a)
Deprecated.Please usetoArray()
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
float[] toArray(float[] 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(FloatCollection 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(FloatCollection 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(FloatCollection 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 Float> filter)
Deprecated.Please use the corresponding type-specific method instead.- Specified by:
removeIf
in interfaceCollection<Float>
-
removeIf
default boolean removeIf(DoublePredicate filter)
Remove from this collection all elements which satisfy the given predicate.- Parameters:
filter
- a predicate which returnstrue
for elements to be removed.- Returns:
true
if any elements were removed.- See Also:
Collection.removeIf(java.util.function.Predicate)
-
retainAll
boolean retainAll(FloatCollection 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.- See Also:
