FONode.FONodeIterator (Apache FOP 2.1 API)

All Superinterfaces:

java.util.Iterator<FONode>, java.util.ListIterator<FONode>

All Known Implementing Classes:

FObj.FObjIterator

Enclosing class:

FONode
```
public static interface FONode.FONodeIterator
extends java.util.ListIterator<FONode>
```
Base iterator interface over a FO's children, offering three methods on top of the base interface methods {@see java.util.ListIterator}.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	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`.
