NAME

       RpcPeer - support bi-directional RPC between two services

SYNOPSIS

       #include <Dispatch/rpcpeer.h>

DESCRIPTION

       An  RpcPeer (actually, an instance of a derived class) tries to open a connection to another RpcPeer.  If the other RpcPeer is not yet run-
       ning, the RpcPeer will create its own port and wait for the other RpcPeer to open a connection.	When either RpcPeer  opens  a  connection,
       each RpcPeer will create both a reader and a writer so each RpcPeer can send RPC requests to its opposite over the same connection.

CONSTRUCTOR

       RpcPeer(const char* lPath, int lPort = 0)
	      Store  the arguments for later use since a base constructor can't call a derived class's virtual function.  The derived class's con-
	      structor should call ``init'', described below.

       void init(const char* rPath)
	      Find the host name and port number registered by the other RpcPeer and try to open a connection to it.  If it's not running,  create
	      our own port and wait for the other RpcPeer to open a connection.

PUBLIC OPERATIONS

       void run()
       void quitRunning()
	      Read  RPC  requests  continuously  until	``quitRunning()'' terminates the loop.	If you're using InterViews, you don't have to call
	      ``run()'' since the InterViews event-reading code will also read RPC requests.

PROTECTED OPERATIONS

       virtual boolean createReaderAndWriter(const char* rHost, int rPort) = 0
       virtual void createReaderAndWriter(int fd) = 0
	      You must define both functions in a derived class in order to start reading and writing RPC requests over the connection.  Typically
	      both functions would create a writer using the given parameters and then attach a reader to the writer's rpcstream.

NAME

       Event::RPC::Connection - Represents a RPC connection

SYNOPSIS

       Note: you never create instances of this class in your own code, it's only used internally by Event::RPC::Server. But you may request
       connection objects using the connection_hook of Event::RPC::Server and then having some read access on them.

	 my $connection = Event::RPC::Server::Connection->new (
	     $rpc_server, $client_socket
	 );

       As well you can get the currently active connection from your Event::RPC::Server object:

	 my $server	= Event::RPC::Server->instance;
	 my $connection = $server->get_active_connection;

DESCRIPTION

       Objects of this class represents a connection from an Event::RPC::Client to an Event::RPC::Server instance. They live inside the server and
       the whole Client/Server protocol is implemented here.

READ ONLY ATTRIBUTES

       The following attributes may be read using the corresponding get_ATTRIBUTE accessors:

       cid The connection ID of this connection. A number which is unique for this server instance.

       server
	   The Event::RPC::Server instance this connection belongs to.

       is_authenticated
	   This boolean value reflects whether the connection is authenticated resp. whether the client passed correct credentials.

       auth_user
	   This is the name of the user who was authenticated successfully for this connection.

       client_oids
	   This is a hash reference of object id's which are in use by the client of this connection. Keys are the object ids, value is always 1.
	   You can get the corresponding objects by using the

	     $connection->get_client_object($oid)

	   method.

	   Don't change anything in this hash, in particular don't delete or add entries. Event::RPC does all the necessary garbage collection
	   transparently, no need to mess with that.
