TCustomJsonConverter Class
Abstract base class for custom JSON converters.
Remarks
Subclass TCustomJsonConverter to implement a converter that handles serialization and deserialization of a specific type. The default implementations of WriteJson and ReadJson write and read null respectively, so descendants should override them to provide meaningful behavior.
