ValueToJSON¶

Converts a TValue to a JSON data structure

Declaration¶

Source position: fpjsonvalue.pp line 31

function ValueToJSON(const aValue: TValue; aType: TRttiType) : TJSONData;

Arguments¶

Name	Description
aValue	The TValue record to convert to JSON
aType	The RTTI type information for the value being converted

Function result¶

The JSON data structure representing the converted value

Description¶

ValueToJSON converts a TValue record to its corresponding JSON representation using the provided RTTI type information. The function supports conversion of strings (AnsiString, UnicodeString, WideString, ShortString), integers (Integer, Int64, QWord), booleans, and dynamic arrays. For dynamic arrays, the function recursively converts each element using the array's element type information. If an error occurs during conversion, any partially created JSON structure is cleaned up before re-raising the exception.

Errors¶

May raise an exception if the conversion fails or if an unsupported type is encountered.
