public abstract class AbstractShortCollection
extends Object
implements ShortCollection

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.

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