public abstract class AbstractDoubleCollection extends java.util.AbstractCollection<java.lang.Double> implements DoubleCollection
In particular, this class provide iterator()
, add()
, remove(Object)
and
contains(Object)
methods that just call the type-specific counterpart.
Modifier and Type | Method and Description |
---|---|
boolean |
add(double k) |
boolean |
add(java.lang.Double o)
Delegates to the corresponding type-specific method.
|
boolean |
addAll(java.util.Collection<? extends java.lang.Double> c)
Adds all elements of the given collection to this collection.
|
boolean |
addAll(DoubleCollection c)
Adds all elements of the given type-specific collection to this collection.
|
boolean |
contains(double k) |
boolean |
contains(java.lang.Object o)
Delegates to the corresponding type-specific method.
|
boolean |
containsAll(java.util.Collection<?> c)
Checks whether this collection contains all elements from the given collection.
|
boolean |
containsAll(DoubleCollection c)
Checks whether this collection contains all elements from the given type-specific collection.
|
DoubleIterator |
doubleIterator()
Deprecated.
|
boolean |
isEmpty() |
abstract DoubleIterator |
iterator()
Returns a type-specific iterator on the elements of this collection.
|
boolean |
rem(double k)
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. |
boolean |
rem(java.lang.Object o)
Delegates to the corresponding type-specific method.
|
boolean |
remove(java.lang.Object ok)
Delegates to the type-specific
rem() method. |
boolean |
removeAll(java.util.Collection<?> c)
Remove from this collection all elements in the given collection.
|
boolean |
removeAll(DoubleCollection c)
Remove from this collection all elements in the given type-specific collection.
|
boolean |
retainAll(java.util.Collection<?> c)
Retains in this collection only elements from the given collection.
|
boolean |
retainAll(DoubleCollection c)
Retains in this collection only elements from the given type-specific collection.
|
java.lang.Object[] |
toArray() |
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.
|
double[] |
toDoubleArray(double[] a)
Returns a primitive type array containing the items of this collection.

strengthened in the corresponding type-specific class,
