Jason E Bailey commented on SLING-8271:
---------------------------------------
Before pulling this, I think this is a bit limited in scope and could be
improved with a Predicate object to determine the ability to descend. In a
similar way to
[https://github.com/apache/sling-org-apache-sling-resource-filter/blob/master/src/main/java/org/apache/sling/resource/filter/ResourceStream.java]
You could just extend it to accept(visitor, predicate) and that would allow you
to define a predicate inline in your source
> Improve AbstractResourceVisitor to allow to stop visiting child resources

> 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.
