Description

TJSONParserHandler is a callback prototype used by the GetJSON function to do the actual parsing. It has 2 arguments: AStream, which is the stream containing the JSON that must be parsed, and AUseUTF8, which indicates whether the (ansi) strings contain UTF-8.

The result should be returned in Data.

The parser is expected to use the JSON class types registered using the SetJSONInstanceType method, the actual types can be retrieved with GetJSONInstanceType
