XML read/write is much slower than access of other class instances. If you're going to do lots of reading and writing, I would consider converting the XML data to object data.

The example code was retrieving a node from the graph. I don't need weakKeys because the node set is controlled. Anything in the Dictionary that would be eligible for collection would have necessarily already been removed from the Dictionary. So in the case of XML I'm now assigning a UID to an attribute of the XML and using the value of that attribute as the key. It didn't give me the performance increase I was hoping for, but it is better. If an Object were faster than a Dictionary I would switch over, but if they're equivalent I'll keep the Dictionary to key the Class more generalized. - Daniel Freiman On Tue, May 27, 2008 at 12:02 PM, Christophe Jolif <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: Alex, Alex Harui wrote: > Dictionary keys should be objects. That's why I advised him to use Array not Dictionary... I must admit I don't know exactly what Daniel wants to do but his method name (getItem) reminds me a lot of similar things in Adobe Flex SDK such as ListBase.itemToItemRenderer method that are exactly doing what I propose. That's why I suggested him that workaround.
