This is particularly relevant for extensions. camelcase_name: (str) Camelcase name of this field. index: (int) Dense, 0-indexed index giving the order that this field textually appears within its message in the .proto file. number: (int) Tag number declared for this field in the .proto file. type: (One of the TYPE_* constants below) Declared type. cpp_type: (One of the CPPTYPE_* constants below) C++ type used to represent this field. label: (One of the LABEL_* constants below) Tells whether this field is optional, required, or repeated. has_default_value: (bool) True if this field has a default value defined, otherwise false. default_value: (Varies) Default value of this field. Only meaningful for non-repeated scalar fields. Repeated fields should always set this to [], and non-repeated composite fields should always set this to None. containing_type: (Descriptor) Descriptor of the protocol message type that contains this field. Set by the Descriptor constructor if we're passed into one. Somewhat confusingly, for extension fields, this is the descriptor of the EXTENDED message, not the descriptor of the message containing this field. (See is_extension and extension_scope below). message_type: (Descriptor) If a composite field, a descriptor of the message type contained in this field. Otherwise, this is None. enum_type: (EnumDescriptor) If this field contains an enum, a descriptor of that enum. Otherwise, this is None. is_extension: True iff this describes an extension field. extension_scope: (Descriptor) Only meaningful if is_extension is True. Gives the message that immediately contains this extension field. Will be None iff we're a top-level (file-level) extension field. options: (descriptor_pb2.FieldOptions) Protocol message field options or None to use default field options. containing_oneof: (OneofDescriptor) If the field is a member of a oneof union, contains its descriptor. Otherwise, None. file: (FileDescriptor) Reference to file descriptor.  i8JiNNTcCs*tjj| rtjj|Stjj|SdS)N)rrDrErFFindExtensionByNameFindFieldByName)rr7r8indexrPtypecpp_typelabel default_value message_typer`r: is_extensionr\r*r+has_default_valuecontaining_oneof json_namer9r r r r s  zFieldDescriptor.__new__cstt|j||d||_||_||_d|_|dkr@t||_n||_||_ ||_ ||_ ||_ ||_ ||_||_| |_| |_| |_| |_| |_||_tjdkr| rtjj||_qtjj||_nd|_dS)aThe arguments are as described in the description of FieldDescriptor attributes above.
