Class AbstractResourceVisitor

java.lang.Object

org.apache.sling.api.resource.AbstractResourceVisitor

public abstract class AbstractResourceVisitor
extends Object

This visitor will traverse the given resource and all its children in a depth-first approach and call the visit(Resource) method for each visited resource. It decouples the actual traversal code from application code. Concrete subclasses must implement the visit(Resource) method. There is no possibility to stop traversal in this visitor. If you want to skip certain parts of the subtree or stop traversal at a certain point rather use ResourceStream or ResourceFilterStream.

Since:

2.2 (Sling API Bundle 2.2.0)
