Class RecursiveElementVisitor

java.lang.Object

com.hp.hpl.jena.sparql.syntax.RecursiveElementVisitor

All Implemented Interfaces:

ElementVisitor

public class RecursiveElementVisitor
extends Object
implements ElementVisitor

Visitor pattern helper that walks the entire tree calling operations are various points in the walking process. It is a depth first traversal.

Every visit operation is bracketted by a start/end pair makeing the calling points:

• start of element
• start each sub element
• end of each sub element
• end of element

The calls before and after subElements pass in the containing Element. These calls are in addition to the start/end call on elements as part of the recursive walk.

Usage: inherit from this class and implement startElement/endElement as needed. The ElementWalker is like implementing endElement.
