Class AbstractDepthFirstVisitor

java.lang.Object
  extended by net.sf.ehcache.config.generator.model.AbstractDepthFirstVisitor
All Implemented Interfaces:
NodeElementVisitor
Direct Known Subclasses:
XMLGeneratorVisitor

public abstract class AbstractDepthFirstVisitor
extends Object
implements NodeElementVisitor

Implementation of NodeElementVisitor that does a depth-first traversal of the element. Depth first means the visit starts at the element and goes deeper and deeper in each child element until there are no children and then backtracks, doing the same thing for each children in each child element. This class is an abstract class and provides empty methods that sub-classes can override as needed. The visit methods in this class are called in this order for each element visited by this visitor:
