Method Details

contains

public boolean contains(float k)

Description copied from class: AbstractFloatCollection

Returns true if this collection contains the specified element.

This implementation iterates over the elements in the collection, looking for the specified element.

Specified by:

contains in interface FloatCollection

Overrides:

contains in class AbstractFloatCollection

See Also:

Collection.contains(Object)

remove

public boolean remove(float k)

Description copied from class: AbstractFloatSet

Removes an element from this set.

Note that the corresponding method of a type-specific collection is rem(). This unfortunate situation is caused by the clash with the similarly named index-based method in the List interface. Delegates to the type-specific rem() method implemented by type-specific abstract Collection superclass.

Specified by:

remove in interface FloatSet

Overrides:

remove in class AbstractFloatSet

See Also:

Collection.remove(Object)

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 Collection<Float>

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 Set<Float>

Specified by:

iterator in class AbstractFloatSet

Returns:

a type-specific iterator on the elements of this collection.

See Also:

Iterable.iterator()

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>

addAll

public boolean addAll(Collection<? extends Float> c)

Specified by:

addAll in interface Collection<Float>

Specified by:

addAll in interface Set<Float>

Overrides:

addAll in class AbstractCollection<Float>

removeAll

public boolean removeAll(Collection<?> c)

Specified by:

removeAll in interface Collection<Float>

Specified by:

removeAll in interface Set<Float>

Overrides:

removeAll in class AbstractCollection<Float>

retainAll

public boolean retainAll(Collection<?> c)

Specified by:

retainAll in interface Collection<Float>

Specified by:

retainAll in interface Set<Float>

Overrides:

retainAll in class AbstractCollection<Float>

addAll

public boolean addAll(FloatCollection c)

Description copied from interface: FloatCollection

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 interface: FloatCollection

Remove from this collection all elements in the given type-specific collection.

Specified by:

removeAll in interface FloatCollection

Overrides:

removeAll in class AbstractFloatCollection

Parameters:

c - a type-specific collection.

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 interface: FloatCollection

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)

clone

public Object clone()
