Interface ItemVisitor

All Known Implementing Classes:
ChildrenCollector, ChildrenCollectorFilter, FilteringItemVisitor, TraversingItemVisitor, TraversingItemVisitor.Default
public interface ItemVisitor
This interface defines two signatures of the visit method; one taking a Node, the other a Property. When an object implementing this interface is passed to Item.accept(ItemVisitor visitor) the appropriate visit method is automatically called, depending on whether the Item in question is a Node or a Property. Different implementations of this interface can be written for different purposes. It is, for example, possible for the visit(Node node) method to call accept on the children of the passed node and thus recurse through the tree performing some operation on each Item.
