before returning to the caller. Callbacks are called in the current thread context, so will be associated with the curren transaction and use

Interface : TransferDefinition 3.3
Simply has a collection of nodeRefs to transfer!
/** * Set which nodes to transfer * @param nodes */ public void setNodes(Collection<NodeRef> nodes) { this.nodes = new HashSet<NodeRef>(nodes); } public void setNodes(NodeRef...nodes) { this.setNodes(Arrays.asList(nodes)); }

Interface : NodeCrawler
public interface NodeCrawler{ public abstract Set<NodeRef> crawl(NodeRef... nodes);
public abstract Set<NodeRef> crawl(Set<NodeRef> startingNodes);
public abstract void setNodeFinders(NodeFinder... finders);
public abstract void setNodeFilters(NodeFilter... filters);}

Transfer Service Gotchas ?
Transfer Service
•Don’t try to transfer the entire company home•Don’t transfer to yourself•All nodes need a parent•Replication service is only transferring files / folders and following cm:contains.
48
Transfer Service Future ?
Transfer Service
•Pull transfer as well as push•Transfer model elements as required•Change log•Transaction batching / splitting•Queue Transfers•Transfer out of Alfresco (Similar to Standalone Deployment Receiver)•More transformations (ACL mapping etc)http://wiki.alfresco.com/wiki/Transfer_Service#Wish_List
