#3026:

  • deleted: ConvertableAttribute, DummyConverter, ObjectExtensions
  • renamed: CustomJsonWriter -> SingleLineArrayJsonWriter, JCInstantiator -> JsonTemplateInstantiator
  • added: JsonItemConverterFactory, UnsupportedJsonItem
  • IJsonItemConverter:
    • added two new properties: Priority and ConvertableType -> because converters are automatically collected by plugin infrastructure now
    • Extract, Inject references a root converter now -> typically an instance of JsonItemConverter -> to prevent cycles
  • JsonItemConverter:
    • now implements the interface IJsonItemConverter
    • is now a dynamic class
    • is only instantiable with an factory (JsonItemConverterFactory)
    • still has the old (but now public) static methods Extract and Inject (without ref param IJsonItemConverter root) -> creates instance with factory and calls methods of instance
    • removed register and unregister methods, because the factory collects all converters automatically now (on first call of Create)
    • has cycle detection for Extract and Inject
    • renamed method Get to GetConverter
