Saving defined properties

Hi, (Delphi2009 ent)

I noticed that DefineProperties are not stored by default in the streamer?
Was this intended?
We wanted to use in TComponent save/restore.

thank you,
Vojko

Yes, since it will save the content as plain binary, it is not very JSON friendly.

You would rather use custom JSON serialization, as stated in http://blog.synopse.info/post/2012/04/1 … -any-class

You may write your custom serializer which will call DefineProperties and save the content as a JSON base64 content.

Maybe just a global setting or when HumanReadable=False ?.
Defined IS part of Delphi's component structure.
IMHO it's better to get accurate object snapshot.

Good idea.

I'll add it to the roadmap.
I think it should be enabled by default, for any TComponent which supports it.

Hi,

is there any way to implement this ?
This would be major enhancement in streaming existing components.

I'll create ticket for it -> http://synopse.info/fossil/tktview/3369 … fb5c6f49a1

thank you, Vojko

For ORM level, I suspect a BLOB storage could be a good idea, serialized as JSON using Base64 encoding?

What is your exact need?
Streaming components into/from JSON?
Storing TPersistent properties of a TSQLRecord ORM table?

Streaming components into/from JSON? -> Yes
Storing TPersistent properties of a TSQLRecord ORM table? -> Yes

Yes it can be BLOB storage.

thank you, vojko
