Re: RFC Nested Set manipulation class

If there are no comments this time it's really no problem and I will asume that there is simply no common interest in this package. The package helps with manipulating nested sets. It also allows to move and copy trees and subtrees and it implements a callback mechanism to call other methods on node move, delete, etc..

Sounds interesting, but have you got any examples of how to use it. I guess it's for handling table records in a single table eg a table of employees with parent manager links. Re the callback facility. Wouldn't it be better to define an 'addEventListener($eventType, &$eventListener)' and dispatch/triggerEvent($eventType) methods and an eventListener interface from which eventListeners could inherit. Might make things simpler. -RichardW. -- Richard Wall www.the-moon.net
