aS A 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')()

�SymbolDatabasez'A database of Python generated symbols.c �R � |j }|| j |< | � |� � |S )a@ Registers the given message type in the local database.
Calls to GetSymbol() and GetMessages() will return messages registered here.
Args:
message: A :class:`google.protobuf.message.Message` subclass (or
instance); its descriptor will be registered.
Returns:
The provided message.

Currently, this method only returns message.Message instances, however, if
may be extended in future to support other symbol types.
Args:
symbol (str): a protocol buffer symbol.
Returns:
A Python class corresponding to the symbol.
Raises:
KeyError: if the symbol could not be found.

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 (list[str]): The file names to extract messages from.
Returns:
A dictionary mapping proto names to the message classes.
Raises:
KeyError: if a file could not be found.
