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')() � )�descriptor_pool)�message_factoryc @ sH e Zd ZdZdd� Zdd� Zdd� Zdd � Zd d � Zd d � Z dd� Z dS )�SymbolDatabasez'A database of Python generated symbols.c C s |j }|| j|< | j|� |S )z�Registers the given message type in the local database.

Only messages already created and registered will be returned; (this is the case for imported _pb2 modules) But unlike MessageFactory, this version also returns already defined nested messages, but does not register any message extensions. Args: files: The file names to extract messages from. Returns: A dictionary mapping proto names to the message classes.
