Method Detail

add

public boolean add(double k)

Description copied from interface: DoubleCollection

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

Specified by:

add in interface DoubleCollection

See Also:

Collection.add(Object)

rem

public boolean rem(double k)

Description copied from interface: DoubleCollection

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 DoubleCollection

See Also:

Collection.remove(Object)

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)

Description copied from interface: DoubleCollection

Returns true if this collection contains the specified element.

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.

See Also:

Iterable.iterator()

clear

public void clear()

Specified by:

clear in interface Collection<Double>

toArray

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

Specified by:

toArray in interface Collection<Double>

toArray

public Object[] toArray()

Specified by:

toArray in interface Collection<Double>

containsAll

public boolean containsAll(Collection<?> c)

Specified by:

containsAll in interface Collection<Double>

addAll

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

Specified by:

addAll in interface Collection<Double>

removeAll

public boolean removeAll(Collection<?> c)

Specified by:

removeAll in interface Collection<Double>

retainAll

public boolean retainAll(Collection<?> c)

Specified by:

retainAll in interface Collection<Double>

add

@Deprecated
public boolean add(Double k)

Deprecated.

Description copied from interface: DoubleCollection

Specified by:

contains

@Deprecated
public boolean contains(Object k)

Deprecated.

Description copied from interface: DoubleCollection

Specified by:

remove

@Deprecated
public boolean remove(Object k)

Deprecated.

Description copied from interface: DoubleCollection

Specified by:

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

@Deprecated
public double[] toDoubleArray(double[] a)

Deprecated.

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 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 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[])

containsAll

public boolean containsAll(DoubleCollection c)

Description copied from interface: DoubleCollection

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

Specified by:

containsAll in interface DoubleCollection

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(DoubleCollection c)

Description copied from interface: DoubleCollection

Adds all elements of the given type-specific collection to this collection.

Specified by:

addAll in interface DoubleCollection

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(DoubleCollection c)

Description copied from interface: DoubleCollection

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

Specified by:

removeAll in interface DoubleCollection

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(DoubleCollection c)

Description copied from interface: DoubleCollection

Retains in this collection only elements from the given type-specific collection.

Specified by:

retainAll in interface DoubleCollection

Parameters:

c - a type-specific collection.

Returns:

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