Circular references

[jkgh]

One great and wise ones [yes, I want something!], My object model has the possibility, or should I say probability, of circular references. I'm after two circular reference detection algoritms: one thorough and probably relatively slow, and the other which can be run on the fly at object pointer change. Does the second one exist? Could anyone help [pretty] please! Al When a man goes on a date he wonders if he is going to get lucky. A woman already knows - Frederick Ryder
