Method Detail

add

public boolean add(double k)
Specified by:
add in interface DoubleCollection
Overrides:
add in class AbstractDoubleCollection

contains

public boolean contains(double k)
Specified by:
contains in interface DoubleCollection
See Also:
Collection.contains(Object)

addAll

public boolean addAll(List l)

addAll

public boolean addAll(Collection c)
Description copied from class: AbstractDoubleCollection
Adds all elements of the given collection to this collection.

Specified by:
addAll in interface Set
Overrides:
addAll in class AbstractDoubleCollection
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: AbstractDoubleCollection
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 Set
Overrides:
removeAll in class AbstractDoubleCollection
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: AbstractDoubleCollection
Retains in this collection only elements from the given collection.

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

addAll

public boolean addAll(DoubleList l)

addAll

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

Specified by:
addAll in interface DoubleCollection
Overrides:
addAll in class AbstractDoubleCollection
Parameters:
c - a type-specific collection.
Returns:
true if this collection changed as a result of the call.

removeAll

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

Specified by:
removeAll in interface DoubleCollection
Overrides:
removeAll in class AbstractDoubleCollection
Parameters:
c - a type-specific collection.
Returns:
true if this collection changed as a result of the call.

retainAll

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

Specified by:
retainAll in interface DoubleCollection
Overrides:
retainAll in class AbstractDoubleCollection
Parameters:
c - a type-specific collection.
Returns:
true if this collection changed as a result of the call.

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
Overrides:
toDoubleArray in class AbstractDoubleCollection

doubleIterator

public DoubleIterator doubleIterator()
Description copied from interface: DoubleCollection
Returns a type-specific iterator on the collection.

The iterator returned by the Collection.iterator() method and by this method are identical; however, using this method you can save a type casting.

Specified by:
doubleIterator in interface DoubleCollection
See Also:
Collection.iterator()

size

public int size()
Specified by:
size in interface Set

clone

public Object clone()
