public abstract class AbstractBooleanCollection extends java.util.AbstractCollection<java.lang.Boolean> implements BooleanCollection
In particular, this class provide iterator()
, add()
, remove(Object)
and
contains(Object)
methods that just call the type-specific counterpart.
Warning: Because of a name clash between the list and collection interfaces
the type-specific deletion method of a type-specific abstract
collection is rem()
, rather then remove()
. A
subclass must thus override rem()
, rather than
remove()
, to make all inherited methods work properly.
Modifier and Type | Method and Description |
---|---|
boolean |
add(boolean k)
Ensures that this collection contains the specified element (optional operation).
|
boolean |
add(java.lang.Boolean key)
Deprecated.
Please use the corresponding type-specific method instead.
|
boolean |
addAll(BooleanCollection c)
Adds all elements of the given type-specific collection to this collection.
|
boolean |
addAll(java.util.Collection<? extends java.lang.Boolean> c) |
boolean |
contains(boolean k)
Returns
true if this collection contains the specified element. |
boolean |
contains(java.lang.Object key)
Deprecated.
Please use the corresponding type-specific method instead.
|
boolean |
containsAll(BooleanCollection c)
Checks whether this collection contains all elements from the given type-specific collection.
|
boolean |
containsAll(java.util.Collection<?> c) |
abstract BooleanIterator |
iterator()
Returns a type-specific iterator on the elements of this collection.
|
boolean |
rem(boolean k)
Removes a single instance of the specified element from this
collection, if it is present (optional operation).
|
boolean |
remove(java.lang.Object key)
Deprecated.
Please use the corresponding type-specific method instead.
|
boolean |
removeAll(BooleanCollection c)
Remove from this collection all elements in the given type-specific collection.
|
boolean |
removeAll(java.util.Collection<?> c) |
boolean |
retainAll(BooleanCollection c)
Retains in this collection only elements from the given type-specific collection.
|
boolean |
retainAll(java.util.Collection<?> c) |
boolean[] |
toArray(boolean[] a)
Returns an array containing all of the elements in this collection; the runtime type of the returned array is that of the specified array.
|
boolean[] |
toBooleanArray()
Returns a primitive type array containing the items of this collection.
|
boolean[] |
toBooleanArray(boolean[] a)
Deprecated.
Please use
toArray() instead—this method is redundant and will be removed in the future. |

Note that this method should be called remove()

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()
.
