double[]	toArray(double[] a) Returns a primitive type array containing the items of this collection.
<T> T[]	toArray(T[] a) Returns an containing the items of this collection; the runtime type of the returned array is that of the specified array.
double[]	toDoubleArray() Returns a primitive type array containing the items of this collection.

Method Detail

size

public int size()

Specified by:

size in interface Collection<Double>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Collection<Double>

contains

public boolean contains(double o)

Specified by:

contains in interface DoubleCollection

See Also:

Collection.contains(Object)

iterator

public DoubleIterator iterator()

Description copied from interface: DoubleCollection

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 DoubleCollection

Specified by:

iterator in interface DoubleIterable

Specified by:

iterator in interface Iterable<Double>

Specified by:

iterator in interface Collection<Double>

Returns:

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

doubleIterator

@Deprecated
public DoubleIterator doubleIterator()

Deprecated.

Description copied from interface: DoubleCollection

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

Specified by:

doubleIterator in interface DoubleCollection

See Also:

DoubleCollection.iterator()

add

public boolean add(double k)

Specified by:

add in interface DoubleCollection

See Also:

remove

public boolean remove(Object ok)

Specified by:

remove in interface Collection<Double>

addAll

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

Specified by:

toString

public String toString()

Overrides:

toString in class Object

toArray

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

Description copied from interface: DoubleCollection

Returns an containing the items of this collection; the runtime type of the returned array is that of the specified array.

Warning: 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 DoubleCollection

Specified by:

toArray in interface Collection<Double>

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 Object[] toArray()

Specified by:

toArray in interface Collection<Double>

toDoubleArray

public double[] toDoubleArray()

Description copied from interface: DoubleCollection

Returns a primitive type array containing the items of this collection.

Specified by:

toDoubleArray in interface DoubleCollection

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray()

toDoubleArray

public double[] toDoubleArray(double[] a)

Description copied from interface: DoubleCollection

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:

toDoubleArray in interface DoubleCollection

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 double[] toArray(double[] a)

Description copied from interface: DoubleCollection

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:

toArray in interface DoubleCollection

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[])

rem

public boolean rem(double k)

Description copied from interface: DoubleCollection

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().
