Examples of DOMElementVisitor

com.intellij.util.xml.DomElementVisitor
Visitor is a very common design pattern. DOM model also has a visitor and it's called DomElementVisitor. The {@link DomElement} interface has methods {@link DomElement#accept(DomElementVisitor)}and {@link DomElement#acceptChildren(DomElementVisitor)}taking this visitor as a parameter.
DomElementVisitor has only one method: {@link #visitDomElement(DomElement)}. Where is the Visitor pattern? Where are all those methods with names like visitT(T) that are usually found in it? There are no such methods, because the actual interfaces (T's) arent known to anyone except you. But when you instantiate the DomElementVisitor interface, you may add your own visitT() methods and they will be called! You may even name them just visit(), specify the type of the parameter and everything will be fine.
For example, if you have two DOM element classes - Foo and Bar- your visitor may look like this:
```
 class MyVisitor implements DomElementVisitor { void visitDomElement(DomElement element) {} void visitFoo(Foo foo) {} void visitBar(Bar bar) {} } 
```

org.milyn.delivery.dom.DOMElementVisitor
Element Visitor (GoF) interface for DOM.
{@link SmooksDOMFilter} filters (analyses/transforms) XML/XHTML/HTML contentby "visting" the DOM {@link org.w3c.dom.Element} nodes through a series of iterations overthe source XML DOM.
This interface defines the methods for a "visiting" filter. Implementations of this interface provide a means of hooking analysis and transformation logic into the {@link SmooksDOMFilter} filtering process.
Implementations should be annotated with the {@link org.milyn.delivery.dom.Phase}annotation, indicating in which of the {@link SmooksDOMFilter Visit Phases} the visitor should be applied. If notannotated, the visitor is applied during the Processing phase. The phase may also be specified via the "VisitPhase" property on the {@link org.milyn.cdr.SmooksResourceConfiguration resource configuration}. Valid values in this case are "ASSEMBLY" and "PROCESSING".
Implementations must be stateless. If state storage is required, attach the state to the supplied {@link org.milyn.container.ExecutionContext}. @author tom.fennelly@gmail.com

        result.add(new StructureViewTreeElement(domElement));
