Properties

• item : Item

  Item between old and new positions of TreeWalker.

• length : Number

  Length of the item. For 'elementStart' and 'character' it is 1. For 'text' it is the length of the text. For 'elementEnd' it is undefined.

• nextPosition : Position

  Next position of the iterator.

  • Forward iteration: For 'elementStart' it is the first position inside the element. For all other types it is the position after the item.
  • Backward iteration: For 'elementEnd' it is last position inside element. For all other types it is the position before the item.

• previousPosition : Position

  Previous position of the iterator.

  • Forward iteration: For 'elementEnd' it is the last position inside the element. For all other types it is the position before the item. Note that it is more efficient to use this position then calculate the position before the node using createBefore. It is also more efficient to get the position after node by shifting previousPosition by length, using getShiftedBy, then calculate the position using createAfter.
  • Backward iteration: For 'elementStart' it is the first position inside the element. For all other types it is the position after item.

• type : TreeWalkerValueType
