@martin in my example, http://pastebin.com/6f7HXFcR
we use it among other for lazy loading on properties access, we also have a
custom "garbage collector" based on properties access (
http://pastebin.com/c2rBSUq5), we "reset" init values when object is saved
to server (http://pastebin.com/E6DPCPDr) etc.
This code is core for our application but it's old and very stable so I
can't remember exactly why we've made this choice...
This part of the application is a sort of orm, we can filter objects, load
and save data, add relations to objects and there is no need to develop any
client-server specif code if we add a new class of objects or if we change
properties.
Maybe there is a better way of doing this but this one is well-tried, has
test-cases and is tens of thousands lines...
Sincerely,
David
