Re: [Exist-open] resource iterator

Hi,

It depends on: 1) if you are accessing a remote server or an embedded
instance and 2) the type of the data in the resource set.

If the server is remote, RemoteResourceIterator will be used. If the
resource set contains nodes, they will not be returned to the client
immediately. Instead, the server just returns a unique id, which can
later be used by the iterator to retrieve the serialized node.
Contrary to this, atomic values will be returned immediately.

RemoteResourceSet only caches the ids of the nodes in the node set,
not the nodes or documents themselves.
