Method Summary
 void add(char value)
          Inserts the specified element into my underlying collection (optional operation).
 boolean hasNext()
          Returns true iff I have more elements when traversed in the forward direction.

          Returns true iff I have more elements when traversed in the reverse direction.
 char next()
          Returns the next element in me when traversed in the forward direction.
 int nextIndex()
          Returns the index of the element that would be returned by a subsequent call to CharListIterator.next(), or the number of elements in my iteration if I have no next element.
 char previous()
          Returns the next element in me when traversed in the reverse direction.
 int previousIndex()
          Returns the index of the element that would be returned by a subsequent call to CharListIterator.previous(), or -1 if I have no previous element.
 void remove()
          Removes from my underlying collection the last element returned by CharListIterator.next() or CharListIterator.previous() (optional operation).
 void set(char value)

Method Detail

hasNext

public boolean hasNext()
Description copied from interface: CharListIterator
Returns true iff I have more elements when traversed in the forward direction. (In other words, returns true iff a call to CharListIterator.next() will return an element rather than throwing an exception.

Specified by:
hasNext in interface CharIterator
Specified by:
hasNext in interface CharListIterator
Returns:
true iff I have more elements when traversed in the forward direction

hasPrevious

public boolean hasPrevious()
Description copied from interface: CharListIterator
Returns true iff I have more elements when traversed in the reverse direction. (In other words, returns true iff a call to CharListIterator.previous() will return an element rather than throwing an exception.

Specified by:
hasPrevious in interface CharListIterator
Returns:
true iff I have more elements when traversed in the reverse direction

nextIndex

public int nextIndex()
Description copied from interface: CharListIterator
Returns the index of the element that would be returned by a subsequent call to CharListIterator.next(), or the number of elements in my iteration if I have no next element.

Specified by:
nextIndex in interface CharListIterator
Returns:
the index of the next element in me

previousIndex

public int previousIndex()
Description copied from interface: CharListIterator
Returns the index of the element that would be returned by a subsequent call to CharListIterator.previous(), or -1 if I have no previous element.

Specified by:
previousIndex in interface CharListIterator
Returns:
the index of the previous element in me

next

public char next()
Description copied from interface: CharListIterator
Returns the next element in me when traversed in the forward direction.

Specified by:
next in interface CharIterator
Specified by:
next in interface CharListIterator
Returns:
the next element in me

previous

public char previous()
Description copied from interface: CharListIterator
Returns the next element in me when traversed in the reverse direction.

Specified by:
previous in interface CharListIterator
Returns:
the previous element in me

add

public void add(char value)
Description copied from interface: CharListIterator
Inserts the specified element into my underlying collection (optional operation). The element is inserted immediately before the next element that would have been returned by CharListIterator.next(), if any, and immediately after the next element that would have been returned by CharListIterator.previous(), if any.

The new element is inserted immediately before the implied cursor. A subsequent call to CharListIterator.previous() will return the added element, a subsequent call to CharListIterator.next() will be unaffected. This call increases by one the value that would be returned by a call to CharListIterator.nextIndex() or CharListIterator.previousIndex().

Specified by:
add in interface CharListIterator
Parameters:
value - the value to be inserted

remove

public void remove()
Description copied from interface: CharListIterator
Removes from my underlying collection the last element returned by CharListIterator.next() or CharListIterator.previous() (optional operation).

Specified by:
remove in interface CharIterator
Specified by:
remove in interface CharListIterator

set

public void set(char value)
Description copied from interface: CharListIterator
Replaces in my underlying collection the last element returned by CharListIterator.next() or CharListIterator.previous() with the specified value (optional operation).

Specified by:
set in interface CharListIterator
Parameters:
value - the value to replace the last returned element with
