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.

Handles nested descriptors. Note that this is limited to the scope of defining a message inside of another message. Composite fields can currently only be resolved if the message is defined in the same scope as the field. Args: desc_proto: The descriptor_pb2.DescriptorProto protobuf message. package: Optional package name for the new message Descriptor (string). build_file_if_cpp: Update the C++ descriptor pool if api matches. Set to False on recursion, so no duplicates are created. syntax: The syntax/semantics that should be used. Set to "proto3" to get proto3 field presence semantics. Returns: A Descriptor for protobuf messages. r r r= r� �ascii�.�/z.protoNc S s$ g | ] \}}t |j||jtd ��qS )�r` )r� r1 rc ro )re �iiZenum_valr r r � <listcomp>D s � �z"MakeDescriptor.<locals>.<listcomp>r� F)r� �build_file_if_cppr_ � type_namer' )r8 r� r� r` )r8 r` )/r r� r? r> ZFileDescriptorProtor� �addZ MergeFrom�binasciiZhexlify�os�urandom�decode�pathr� �replacer1 r� r rV ZAddr� rE r� �insertrw r� � enumerater} ro rv �MakeDescriptorru r� r� r� �rfindr� rc r� r� r� r� r� rS �listrk )Z desc_protor� r� r_ r> Zfile_descriptor_protoZ proto_namer� Zfull_message_namerZ Z enum_protorG Z enum_descrY Z nested_protoZ nested_descrX Z field_protor� r� Zfull_type_nameru Z desc_namer r r r� s� � �� � � � �r� )r� TN))r � __author__r r- ZsixZgoogle.protobuf.internalr rE r� r� r� Zgoogle.protobuf.pyextr � Exceptionr r r� r r r r r r+ r, ro Zwith_metaclassr3 rF rS r� r� r� r� r� r� r� rC r� r� r� r� r r r r �<module> sP G9 & ^D,(B0X �
