Method Summary

Methods

Modifier and Type	Method and Description
void	add(FONode newNode) Add the given newNode at the current position.
FONode	first() Returns the first node in the list, and decreases the index, so that a subsequent call to hasPrevious() will return false
boolean	hasNext()
boolean	hasPrevious()
FONode	last() Returns the last node in the list, and advances the current position, so that a subsequent call to hasNext() will return false
FONode	next()
int	nextIndex()
FObj	parent() Returns the parent node for this iterator's list of child nodes
FONode	previous()
int	previousIndex()
void	remove() Removes the node at the current position.
void	set(FONode newNode) Replace the node at the current index with the given newNode.
