TJSONEventReader class

Declaration

Inheritance

1. TJSONEventReader
2. TBaseJSONReader
3. TObject

Description

TJSONEventReader provides event-based JSON reading functionality. It inherits from TBaseJSONReader and fires specific events when different JSON elements are encountered during parsing. This allows applications to process JSON data using an event-driven approach similar to SAX parsing for XML. Each JSON element type has a corresponding event property that can be assigned to handle the parsed data.

Errors

Inherits error handling from TBaseJSONReader. Raises EJSONParser for parsing errors.
