YtjxdZddlZddlmZddlmZddlmZGddZeejZ d ZdS) aSA database of Python protocol buffer generated symbols. SymbolDatabase is the MessageFactory for messages generated at compile time, and makes it easy to create new instances of a registered type, given only the type's protocol buffer symbol name. Example usage:: db = symbol_database.SymbolDatabase() # Register symbols of interest, from one or multiple files. db.RegisterFileDescriptor(my_proto_pb2.DESCRIPTOR) db.RegisterMessage(my_proto_pb2.MyMessage) db.RegisterEnumDescriptor(my_proto_pb2.MyEnum.DESCRIPTOR) # The database can be used as a MessageFactory, to generate types based on # their name: types = db.GetMessages(['my_proto.proto']) my_message_instance = types['MyMessage']() # The database's underlying descriptor pool can be queried, so it's not # necessary to know a type's filename to be able to generate it: filename = db.pool.FindFileContainingSymbol('MyMessage') my_message_instance = db.GetMessages([filename])['MyMessage']() # This functionality is also provided directly via a convenience method: my_message_instance = db.GetSymbol('MyMessage')() N)api_implementation)descriptor_pool)message_factorycHeZdZdZiZd dZdZdZdZdZ dZ d Z d Z dS) SymbolDatabasez'A database of Python generated symbols.Nc:|ptj|_dS)z!Initializes a new SymbolDatabase.N)rDescriptorPoolpool)selfr s ]/var/www/html/CA-Chatbot/venv/lib/python3.11/site-packages/google/protobuf/symbol_database.py__init__zSymbolDatabase.__init__2s8688DIIIcR|j}||j|<|||S)a@Registers the given message type in the local database.
