When a request arrives at the server, the {@link ServerMessageDeliverer}searches in the resource tree for the destination resource. It travels down the resource tree by looking for one element of the destination URI after another and by calling the method {@link #getChild(String)} on each element.It is allowed to override this method and to return an arbitrary resource. This allows for instance to serve URIs with wildcards or delegate requests to any sub-URI to the same resource.
A resource can have its own {@link Executor}. If a resource has such an executor, all requests will be handled by it. Otherwise, the request will be executed on the executor of the parent or transitively the first ancestor that defines its own executor. If no resource up to the root defines its own executor, the currently executing thread will handle the request. A class that implements this interface can export further methods to allow the execution of code on the resource's executor. See {@link ResourceBase} for anexample.
