Description:
 def register_instance(self, instance, allow_dotted_names=False):
 """Registers an instance to respond to XML-RPC requests. Only one instance can be installed at a time. If the registered instance has a _dispatch method then that method will be called with the name of the XML-RPC method and its parameters as a tuple e.g. instance._dispatch('add',(2,3)) If the registered instance does not have a _dispatch method then the instance will be searched to find a matching method and, if found, will be called. Methods beginning with an '_' are considered private and will not be called by SimpleXMLRPCServer. If a registered function matches a XML-RPC request, then it will be called instead of the registered instance. If the optional allow_dotted_names argument is true and the instance does not have a _dispatch method, method names containing dots are supported and resolved, as long as none of the name segments start with an '_'. *** SECURITY WARNING: *** Enabling the allow_dotted_names options allows intruders to access your module's global variables and may allow intruders to execute arbitrary code on your machine. Only use this option on a secure, closed network. """
