Method Detail

add

public boolean add(float k)
Specified by:
add in interface FloatCollection
Overrides:
add in class AbstractFloatCollection
See Also:
Collection.add(Object)

contains

public boolean contains(float k)
Specified by:
contains in interface FloatCollection
Overrides:
contains in class AbstractFloatCollection

addAll

public boolean addAll(Collection<? extends Float> c)
Description copied from class: AbstractFloatCollection
Adds all elements of the given collection to this collection.

Specified by:
addAll in interface Collection<Float>
Specified by:
addAll in interface Set<Float>
Overrides:
addAll in class AbstractFloatCollection
Parameters:
c - a collection.
Returns:
true if this collection changed as a result of the call.

removeAll

public boolean removeAll(Collection<?> c)
Description copied from class: AbstractFloatCollection
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 interface Collection<Float>
Specified by:
removeAll in interface Set<Float>
Overrides:
removeAll in class AbstractFloatCollection
Parameters:
c - a collection.
Returns:
true if this collection changed as a result of the call.

retainAll

public boolean retainAll(Collection<?> c)
Description copied from class: AbstractFloatCollection
Retains in this collection only elements from the given collection.

Specified by:
retainAll in interface Collection<Float>
Specified by:
retainAll in interface Set<Float>
Overrides:
retainAll in class AbstractFloatCollection
Parameters:
c - a collection.
Returns:
true if this collection changed as a result of the call.

toFloatArray

public float[] toFloatArray()
Description copied from interface: FloatCollection
Returns a primitive type array containing the items of this collection.

Specified by:
toFloatArray in interface FloatCollection
Overrides:
toFloatArray in class AbstractFloatCollection
Returns:
a primitive type array containing the items of this collection.
See Also:
Collection.toArray()

addAll

public boolean addAll(FloatCollection c)
Description copied from class: AbstractFloatCollection
Adds all elements of the given type-specific collection to this collection.

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

removeAll

public boolean removeAll(FloatCollection c)
Description copied from class: AbstractFloatCollection
Remove from this collection all elements in the given type-specific collection.

Specified by:
removeAll in interface FloatCollection
Overrides:
removeAll in class AbstractFloatCollection

Returns:
true if this collection changed as a result of the call.
See Also:
Collection.removeAll(Collection)

retainAll

public boolean retainAll(FloatCollection c)
Description copied from class: AbstractFloatCollection
Retains in this collection only elements from the given type-specific collection.

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

iterator

public FloatListIterator iterator()
Description copied from interface: FloatCollection
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 FloatCollection
Specified by:
iterator in interface FloatIterable
Specified by:
iterator in interface FloatSet
Specified by:
iterator in interface Iterable<Float>
Specified by:
iterator in interface Collection<Float>
Specified by:
iterator in interface Set<Float>
Specified by:
iterator in class AbstractFloatSet
Returns:
a type-specific iterator on the elements of this collection.

size

public int size()
Specified by:
size in interface Collection<Float>
Specified by:
size in interface Set<Float>
Specified by:
size in class AbstractCollection<Float>

clone

public Object clone()
Overrides:
clone in class Object
