The iterators for the multiway trees are now implemented as a type hierarchy. Iterating over a tree is the same as iterating over a subtree starting from the root, and so the tree iterator forwards the request to the subtree iterator. Tested on x86_64-pc-linux-gnu, committed on trunk 2011-12-02 Matthew Heaney <heaney@adacore.com> * a-cbmutr.ads (No_Node): Moved declaration from body to spec * a-comutr.adb, a-cimutr.adb, a-cbmutr.adb (Iterator): Derives from Root_Iterator. (Child_Iterator): Derives from Root_Iterator. (Finalize): Implemented as an override operation for Root_Iterator. (First): Return value depends on Subtree component. (Last): Component was renamed from Parent to Subtree. (Next): Checks parameter value, and uses simplified loop. (Iterate): Forwards to Iterate_Subtree. (Iterate_Children): Component was renamed from Parent to Subtree. (Iterate_Subtree): Checks parameter value
