public abstract class AbstractBooleanCollection
extends Object
implements BooleanCollection

An abstract class providing basic methods for collections implementing a type-specific interface.

In particular, this class provide iterator(), add(Object), remove(Object) and contains(Object) methods that just call the type-specific counterpart.

          Delegates to the corresponding type-specific method.
 boolean addAll(BooleanCollection c)
          Adds all elements of the given type-specific collection to this collection.
 boolean addAll(Collection c)
          Adds all elements of the given collection to this collection.
 boolean contains(Object o)
          Delegates to the corresponding type-specific method.
 boolean containsAll(BooleanCollection c)
          Checks whether this collection contains all elements from the given type-specific collection.
 boolean containsAll(Collection c)
          Checks whether this collection contains all elements from the given collection.
 boolean isEmpty()
           
 Iterator iterator()
          Delegates to the corresponding type-specific method.
 boolean remove(boolean k)
           
 boolean remove(Object o)
          Delegates to the corresponding type-specific method.
 boolean removeAll(BooleanCollection c)
          Remove from this collection all elements in the given type-specific collection.
 boolean removeAll(Collection c)
          Remove from this collection all elements in the given collection.
 boolean retainAll(BooleanCollection c)
          Retains in this collection only elements from the given type-specific collection.
 boolean retainAll(Collection c)
          Retains in this collection only elements from the given collection.
 Object[] toArray()
           
 boolean[] toArray(boolean[] a)
          Builds a primitive type array containing the items of this collection.
 Object[] toArray(Object[] a)
           
 boolean[] toBooleanArray()
          Returns a primitive type array containing the items of this collection.
 boolean[] toBooleanArray(boolean[] a)
