- !ruby/struct:SM::Flow::P
body: Module managing the underlying network protocol(s) used by drb.
- !ruby/struct:SM::Flow::P
body: "By default, drb uses the DRbTCPSocket protocol. Other protocols can be defined. A protocol must define the following class methods:"
- !ruby/struct:SM::Flow::VERB
body: " [open(uri, config)] Open a client connection to the server at <tt>uri</tt>,\n using configuration <tt>config</tt>. Return a protocol\n instance for this connection.\n [open_server(uri, config)] Open a server listening at <tt>uri</tt>,\n using configuration <tt>config</tt>. Return a\n protocol instance for this listener.\n [uri_option(uri, config)] Take a URI, possibly containing an option\n component (e.g. a trailing '?param=val'),\n and return a [uri, option] tuple.\n"
- !ruby/struct:SM::Flow::P
body: All of these methods should raise a DRbBadScheme error if the URI does not identify the protocol they support (e.g. "druby:" for the standard Ruby protocol). This is how the DRbProtocol module, given a URI, determines which protocol implementation serves that protocol.
- !ruby/struct:SM::Flow::P
body: "The protocol instance returned by #open_server must have the following methods:"
- !ruby/object:SM::Flow::LIST
contents:
- !ruby/struct:SM::Flow::LI
label: accept
body: Accept a new connection to the server. Returns a protocol instance capable of communicating with the client.
- !ruby/struct:SM::Flow::LI
label: close
body: Close the server connection.
- !ruby/struct:SM::Flow::LI
label: uri
body: Get the URI for this server.
type: :LABELED
- !ruby/struct:SM::Flow::P
body: "The protocol instance returned by #open must have the following methods:"
- !ruby/object:SM::Flow::LIST
contents:
- !ruby/struct:SM::Flow::LI
label: send_request (ref, msg_id, arg, b)
body: Send a request to <tt>ref</tt> with the given message id and arguments. This is most easily implemented by calling DRbMessage.send_request, providing a stream that sits on top of the current protocol.
- !ruby/struct:SM::Flow::LI
label: recv_reply
body: Receive a reply from the server and return it as a [success-boolean, reply-value] pair. This is most easily implemented by calling DRb.recv_reply, providing a stream that sits on top of the current protocol.
- !ruby/struct:SM::Flow::LI
label: alive?
body: Is this connection still alive?
- !ruby/struct:SM::Flow::LI
label: close
body: Close this connection.
type: :LABELED
- !ruby/struct:SM::Flow::P
body: "The protocol instance returned by #open_server().accept() must have the following methods:"
- !ruby/object:SM::Flow::LIST
contents:
- !ruby/struct:SM::Flow::LI
label: recv_request
body: Receive a request from the client and return a [object, message, args, block] tuple. This is most easily implemented by calling DRbMessage.recv_request, providing a stream that sits on top of the current protocol.
- !ruby/struct:SM::Flow::LI
label: send_reply(succ, result)
body: Send a reply to the client. This is most easily implemented by calling DRbMessage.send_reply, providing a stream that sits on top of the current protocol.
- !ruby/struct:SM::Flow::LI
label: close
body: Close this connection.
type: :LABELED
- !ruby/struct:SM::Flow::P
body: A new protocol is registered with the DRbProtocol module using the add_protocol method.
- !ruby/struct:SM::Flow::P
body: For examples of other protocols, see DRbUNIXSocket in drb/unix.rb, and HTTP0 in sample/http0.rb and sample/http0serv.rb in the full drb distribution.
