Method Summary
 void add(byte 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.
 byte 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 ByteListIterator.next(), or the number of elements in my iteration if I have no next element.
 byte 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 ByteListIterator.previous(), or -1 if I have no previous element.
 void remove()
          Removes from my underlying collection the last element returned by ByteListIterator.next() or ByteListIterator.previous() (optional operation).
 void set(byte value)

Method Detail

hasNext

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

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

hasPrevious

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

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

nextIndex

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

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

previousIndex

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

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

next

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

Specified by:
next in interface ByteIterator
Specified by:
next in interface ByteListIterator
Returns:
the next element in me

previous

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

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

add

public void add(byte value)
Description copied from interface: ByteListIterator
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 ByteListIterator.next(), if any, and immediately after the next element that would have been returned by ByteListIterator.previous(), if any.

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

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

remove

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

Specified by:
remove in interface ByteIterator
Specified by:
remove in interface ByteListIterator

set

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

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