public abstract class FilteringItemVisitor
Field Summary | |
---|---|
protected boolean |
breadthFirst
indicates if traversal should be done in a breadth-first manner rather than depth-first (which is the default) |
protected int |
currentLevel
used to track hierarchy level of item currently being processed |
protected LinkedList |
currentQueue
queues used to implement breadth-first traversal |
protected org.apache.commons.collections.Predicate |
includePredicate
Predicate that defines which items are included. |
protected int |
maxLevel
the 0-based level up to which the hierarchy should be traversed (if it's -1, the hierarchy will be traversed until there are no more children of the current item) |
protected LinkedList |
nextQueue
|
protected org.apache.commons.collections.Predicate |
traversalPredicate
Predicate that defines which items are traversed. |
protected boolean |
walkProperties
Do we want to walk all properties of nodes? The default is false. |

It calls TraversingItemVisitor.entering(Property, int)

specify behaviour on 'arrival at' and 'after leaving' the Property

If this method throws, the visiting process is aborted.
