Constructor Details

#initialize(url, query_server_information = false) ⇒ Server

Initialize a Server object at the given URL. Sesame uses a stateless REST protocol, so this will not actually do anything over the network unless query_server_information is true. Loads the protocol version and repositories available on the server if it is.
