NSTreeControllerTreeNode not documented?

Subject: NSTreeControllerTreeNode not documented?
From: Joan Lluch (casa) <email@hidden>

An NSOutlineView which is binded to a NSTreeController gives instances of NSTreeControllerTreeNode in the item (or items) parameter of their datasource or delegate methods. For example:

- (BOOL)outlineView:(NSOutlineView *)outlineView writeItems:(NSArray *)items toPasteboard:(NSPasteboard *)pboard

would give an array of NSTreeControllerTreeNode objects in the items parameter.

- (BOOL)outlineView:(NSOutlineView *)sender isGroupItem:(id)item

would give an instance of a NSTreeControllerTreeNode

As far as I know, this class is not documented. How can I access (or know) the actual object in the NSTreeController that the item is refering to.

I will appreciate any help.
