## org.apache.fop.fo
Class FObj.FObjIterator

    java.lang.Object
      org.apache.fop.fo.FObj.FObjIterator

All Implemented Interfaces:
  FONode.FONodeIterator, java.util.Iterator, java.util.ListIterator

Enclosing class:
  FObj

public class FObj.FObjIterator
extends java.lang.Object
implements FONode.FONodeIterator

Basic `FONodeIterator` implementation

Method Summary
`void` | `add(java.lang.Object o)`
`FONode` | `firstNode()` 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` | `lastNode()` Returns the last node in the list, and advances the current position, so that a subsequent call to `hasNext()` will return `false`
`java.lang.Object` | `next()`
`int` | `nextIndex()`
`FONode` | `nextNode()` Convenience method with return type of FONode (semantically equivalent to: `(FONode) next();`)
`FObj` | `parentNode()` Returns the parent node for this iterator's list of child nodes
`java.lang.Object` | `previous()`
`int` | `previousIndex()`
`FONode` | `previousNode()` Convenience method with return type of FONode (semantically equivalent to: `(FONode) previous();`)
`void` | `remove()`
`void` | `set(java.lang.Object o)`

    public void set(java.lang.Object o)

  Specified by:
    `set` in interface `java.util.ListIterator`

### add

    public void add(java.lang.Object o)

  Specified by:
    `add` in interface `java.util.ListIterator`

### hasNext

    public boolean hasNext()

    public int nextIndex()

  Specified by:
    `nextIndex` in interface `java.util.ListIterator`

### previousIndex

    public int previousIndex()

  Specified by:
    `previousIndex` in interface `java.util.ListIterator`

### remove

    public void remove()

  Specified by:
    `remove` in interface `java.util.ListIterator`

### lastNode

    public FONode lastNode()

  Returns the last node in the list, and advances the current position, so that a subsequent call to `hasNext()` will return `false`

  Specified by:
    `lastNode` in interface `FONode.FONodeIterator`
  Returns:
    the last node in the list

### firstNode

    public FONode firstNode()

  Returns the first node in the list, and decreases the index, so that a subsequent call to `hasPrevious()` will return `false`

  Specified by:
    `firstNode` in interface `FONode.FONodeIterator`
  Returns:
    the first node in the list

### nextNode

    public FONode nextNode()

  Convenience method with return type of FONode (semantically equivalent to: `(FONode) next();`)

  Specified by:
    `nextNode` in interface `FONode.FONodeIterator`
  Returns:
    the next node (if any), as a type FONode

### previousNode

    public FONode previousNode()

  Convenience method with return type of FONode (semantically equivalent to: `(FONode) previous();`)

  Specified by:
    `previousNode` in interface `FONode.FONodeIterator`
  Returns:
    the previous node (if any), as a type FONode
