I wonder what sort of operator overloads are possible (and with what version of Delphi)? Thanks to Hallvard's great write-up on operator overloading, I know of :
However, what I don't know are the names for the '=', '<=', '<', '<>', '>' and '>=' operators. Do these exist, and from what Delphi version can I use these?
PS: I still use Delphi 2009 at the moment, so I would have another strong upgrade-argument if 2010 offers these ;-)
Actually, I found the answer to this myself, but kept the question as I can imagine people will search for this information regularly on stackoverflow;
The official description on operator overloaders can be found here : http://docwiki.embarcadero.com/RADStudio/en/Operator_Overloading_(Delphi)
Mainly, the ones I was looking for are named:
I just put my notes online of a session on nullable types with operator overloading that I gave during a few conferences.
It now contains a table of the operators, the names and what works/doesn't work. WordPress initially malformed that table, but I managed to restore it.
You can also download the full set of slides and source code demos.
In short:
Hope this helps you. Let me know if you need more info: I have done quite a bit of production work with operator overloading.
