o advance()
Advance by one.
o advance(int)
Advance by a specified amount.

Return true if I'm positioned after the last item in my input stream.
o clone()
Return a clone of myself.
o distance(ForwardIterator)
Return the distance from myself to another iterator.
o equals(Object)
Return true if a specified object is the same kind of iterator as me and is positioned at the same element.
o get()
Return the object at my current position.

o getContainer()
Return my associated HashSet
o hasMoreElements()
Return true if there are more elements in my input stream.
o isCompatibleWith(InputIterator)
Return true if both iterator and myself can be used as a range.
o nextElement()
Return the next element in my input stream.
o opaqueData()

o atBegin 
 public boolean atBegin()
Return true if I'm positioned at the first item of my input stream.

o atEnd 
 public boolean atEnd()

o advance 
 public void advance()
Advance by one.

o advance 
 public void advance(int n)
Advance by a specified amount.

Parameters:
n - The amount to advance.
Throws: InvalidOperationException
If the parameter is less than zero.

Throws: NoSuchElementException
If I'm positioned at an invalid position.
o get 
 public Object get()
Return the object at my current position.

o get 
 public Object get(int offset)
Return the object that is a specified distance from my current position.

Parameters:
offset - The offset from my current position.
Throws: InvalidOperationException
If the parameter is less than zero.
o put 
 public void put(int offset,
                 Object object)

Parameters:
offset - The offset from my current position.
object - The object to write.
Throws: InvalidOperationException
If the parameter is less than zero.
o put 
 public void put(Object object)
HashSet the object at my current position to a specified value.

Parameters:
object - The object to be written at my current position.
o distance 
 public int distance(ForwardIterator iterator)
