CustomExportCallback

Optional callback to run when exporting a type which we don't already understand.

Windows

MacOS

Linux

Type

typedef TBaseDelegate_TwoParams< TSharedPtr< FJsonValue >, FProperty *, const void * > CustomExportCallback

References

Include	#include "JsonObjectConverter.h"

Remarks

Optional callback to run when exporting a type which we don't already understand. If this returns a valid pointer it will be inserted into the export chain. If not, or if this is not passed in, then we will call the generic ToString on the type and export as a JSON string.
