> Currently the AbstractResourceVisitor (https://github.com/apache/sling-org-apache-sling-api/blob/master/src/main/java/org/apache/sling/api/resource/AbstractResourceVisitor.java)
completely decouples the {{visit}} method from the actual resource traversal. That means it
is currently rather hard to programmatically add a break condition which should lead to no
further descending into child resources.
> I propose to extend {{AbstractResourceVisitor}} by an additional visit method which is
supposed to return a boolean value. Only if {{true}} is returned it will further descend into
the children of the current resource. The default implementation should just return {{true}}
to make this change backwards compatible.
