What about System.JSON?

[Attila Kovacs 629]

Is this unit deprecated?

 

There is a buch of enums in System.JSON.Types.pas that are not implemented:

 

  TJsonNullValueHandling = (Include, Ignore);

  TJsonDefaultValueHandling = (Include, Ignore, Populate, IgnoreAndPopulate);
  TJsonReferenceLoopHandling = (Error, Ignore, Serialize);

  TJsonObjectCreationHandling = (Auto, Reuse, Replace);

  TJsonTypeNameHandling = (None, Objects, Arrays, All, Auto);
 

TJsonNullValueHandling would be very handy to have.

Should I ask them once the QP is live again, or is this already considered old stuff that won't be continued or supported?

Might possibly be for future implementation. Or maybe these were part of a large group of types or constants imported from a header file of some sort.

 

I found a couple of references that look like there's some relevance:
