Inheritance

1. TBaseJSONReader
2. TObject

Descends from it: TJSONConsumerReader TJSONEventReader TJSONParser

Description

TBaseJSONReader is the abstract base class for all JSON reading functionality. It provides the core parsing logic and virtual methods that must be implemented by derived classes. The class uses TJSONScanner for tokenization and handles the parsing of JSON objects, arrays, and primitive values. Derived classes must implement abstract methods to handle different JSON element types encountered during parsing.

Errors

Raises EJSONParser when invalid JSON syntax is encountered.
