Delphi object persistence, what is the best way

Question

I have developed application for drawing some shapes (lines mostly) , now i need to be able to store sketch to a file, I know that delphi has build in routines for object persi

Answer 1

One method that I have used in the past is to store my object properties in an XML file writing a custom "save" routine which adds to a passed IXMLNode, and a new constructor which reads from a passed IXMLNode. I store component as a node, and the properties as attributes (unless the property is another object, then it would be a child node).

I believe there are some routines in the Delphi Jedi project which will handle component streaming for you, but I have not used them directly as most of my XML streaming has been done by hand since my objects were extremely simple and could be rendered with only a handful of properties.
