public class WorkSet<E>
A WorkSet is a Set offering constant-time
access to the first/last element inserted, and an iterator whose speed
is not dependent on the total capacity of the underlying hashtable.
Conforms to the JDK 1.2 Collections API.
| Constructor Summary | |
|---|---|
WorkSet()
Deprecated. Creates a new, empty WorkSet with a default capacity
and load factor. |
|
WorkSet(Collection<? extends E> c)
Deprecated. Constructs a new WorkSet with the contents of the
specified Collection. |
|
WorkSet(int initialCapacity)
Deprecated. Constructs a new, empty WorkSet with the specified
initial capacity and default load factor. |
|
WorkSet(int initialCapacity,
float loadFactor)
Deprecated. Constructs a new, empty WorkSet with the specified
initial capacity and the specified load factor. |
|
| Method Summary | |
|---|---|
boolean |
add(E o)
Deprecated. Adds the object to the set and returns true if the element is not already present. |
boolean |
addFirst(E o)
Deprecated. Adds an element to the front of the (ordered) set and returns true, if the element is not already present in the set. |
boolean |
addLast(E o)
Deprecated. Adds an element to the end of the (ordered) set and returns true, if the element is not already present in the set. |
void |
clear()
Deprecated. Removes all elements from the set. |
boolean |
contains(Object o)
Deprecated. Determines if this contains an item. |
E |
getFirst()
Deprecated. Returns the first element in the ordered set. |
E |
getLast()
Deprecated. Returns the last element in the ordered set. |
boolean |
isEmpty()
Deprecated. Determines if there are any more items left in this. |
Iterator<E> |
iterator()
Deprecated. Efficient set iterator. |
E |
peek()
Deprecated. Looks at the object as the top of this WorkSet
(treating it as a Stack) without removing it
from the set/stack. |
E |
pop()
Deprecated. Removes the item at the top of this WorkSet
(treating it as a Stack) and returns that object
as the value of this function. |
void |
push(E item)
Deprecated. Pushes item onto the top of this WorkSet (treating
it as a Stack), if it is not already there. |
boolean |
remove(Object o)
Deprecated. |
E |
removeFirst()
Deprecated. Removes the first element in the ordered set and returns it. |
E |
removeLast()
Deprecated. Removes the last element in the ordered set and returns it. |
int |
size()
Deprecated. |

| Method Detail |

public boolean addFirst(E o)
public boolean addLast(E o)
public E getFirst()
public E getLast()
public E removeFirst()
public E removeLast()
public E peek()
WorkSet
(treating it as a Stack) without removing it
from the set/stack.
public E pop()
WorkSet
(treating it as a Stack) and returns that object
as the value of this function.
public void push(E item)
WorkSet (treating
it as a Stack), if it is not already there.
If the item is already in the set/on the stack,
then this method does nothing.
this
item is not already an
element of this, adds
item to this.
Else does nothing.
