Copying property values via rtti

I'd like to be able to copy the (published) property values from a TSynPersistent subclass to a TOrm subclass - only the ones that match by name and type. I've been trawling through the v1 DDD code but have noticed it's not ported to v2. I can see a set of useful functions in the v2 rtti unit but is there anything elsewhere in v2 to simplify this? Or should I just use what's in the rtti unit and roll my own?

Thanks, Bob

Re: Copying property values via rtti

My guess is that CopyObject() from mormot.core.rtti could do this.

But by default, not with the same exact type.
I have added an option to customize CopyObject() overloaded functions.

Re: Copying property values via rtti

I have made a huge refactoring to make it possible.

See the new RecordToObject() and ObjectToRecord() functions:

Re: Copying property values via rtti

I have introduced the new TRttiMap wrapper feature.
It is designed to ease any kind of class/record, class/class or record/record field mapping.
For instance, it is a very good fit for safe and fast DTO process, and is likely to be used in the context of DDD or KDD process, perhaps in a easier way than in mORMot 1.
