Examples of javax.faces.component.UIComponent.visitTree()

javax.faces.component.UIComponent.visitTree()
The visit tree method, visit tree walks over a subtree and processes the callback object to perform some operation on the subtree
there are some details in the implementation which according to the spec have to be in place: a) before calling the callback and traversing into the subtree pushComponentToEL has to be called b) after the processing popComponentFromEL has to be performed to remove the component from the el

The tree traversal optimizations are located in the visit context and can be replaced via the VisitContextFactory in the faces-config factory section
@param context the visit context which handles the processing details @param callback the callback to be performed @return false if the processing is not done true if we can shortcutthe visiting because we are done with everything @since 2.0
