Method Details

add

public boolean add(float k)

Description copied from interface: FloatCollection

Ensures that this collection contains the specified element (optional operation).

Specified by:

add in interface FloatCollection

See Also:

Collection.add(Object)

rem

public boolean rem(float k)

Description copied from interface: FloatCollection

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 the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

Specified by:

rem in interface FloatCollection

See Also:

Collection.remove(Object)

size

public int size()

Specified by:

size in interface Collection<Float>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Collection<Float>

contains

public boolean contains(float o)

Description copied from interface: FloatCollection

Returns true if this collection contains the specified element.

Specified by:

contains in interface FloatCollection

See Also:

Collection.contains(Object)

iterator

public FloatIterator 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 Iterable<Float>

Returns:

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

See Also:

Iterable.iterator()

clear

public void clear()

Specified by:

clear in interface Collection<Float>

toArray

public <T> T[] toArray(T[] a)

Specified by:

toArray in interface Collection<Float>

toArray

public Object[] toArray()

Specified by:

toArray in interface Collection<Float>

containsAll

public boolean containsAll(Collection<?> c)

Specified by:

containsAll in interface Collection<Float>

addAll

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

Specified by:

addAll in interface Collection<Float>

removeAll

public boolean removeAll(Collection<?> c)

Specified by:

removeAll in interface Collection<Float>

retainAll

public boolean retainAll(Collection<?> c)

Specified by:

retainAll in interface Collection<Float>

add

@Deprecated public boolean add(Float k)

Deprecated.

Description copied from interface: FloatCollection

Specified by:

add in interface Collection<Float>

Specified by:

add in interface FloatCollection

contains

@Deprecated public boolean contains(Object k)

Deprecated.

Description copied from interface: FloatCollection

Specified by:

contains in interface Collection<Float>

Specified by:

contains in interface FloatCollection

remove

@Deprecated public boolean remove(Object k)

Deprecated.

Description copied from interface: FloatCollection

Specified by:

remove in interface Collection<Float>

Specified by:

remove in interface FloatCollection

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

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray()

toFloatArray

@Deprecated public float[] toFloatArray(float[] a)

Deprecated.

Description copied from interface: FloatCollection

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.

Specified by:

toFloatArray in interface FloatCollection

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

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 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 interface FloatCollection

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[])

containsAll

public boolean containsAll(FloatCollection c)

Description copied from interface: FloatCollection

Checks whether this collection contains all elements from the given type-specific collection.

Specified by:

containsAll in interface FloatCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection contains all elements of the argument.

See Also:

Collection.containsAll(Collection)

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

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

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

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

Collection.retainAll(Collection)

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Specified by:

hashCode in interface Collection<Float>

Overrides:

hashCode in class Object
