NAME

       X11::Protocol::Connection - Perl module abstract base class for X11 client to server connections

SYNOPSIS

	 # In connection object module
	 package X11::Protocol::Connection::CarrierPigeon;
	 use X11::Protocol::Connection;
	 @ISA = ('X11::Protocol::Connection');
	 sub open { ... }
	 sub give { ... }
	 sub get { ... }
	 sub fh { ... }
	 ...

	 # In program
	 $connection = X11::Protocol::Connection::CarrierPigeon
	   ->open($host, $display_number);
	 $x = X11::Protocol->new($connection);

	 $connection->give($data);

	 $reply = unpack("I", $connection->get(4));

	 use IO::Select;
	 $sel = IO::select->new($connection->fh);
	 if ($sel->can_read == $connection->fh) ...

DESCRIPTION

       This module is an abstract base class for the various X11::Protocol::Connection::* modules that provide connections to X servers for the
       X11::Protocol module. It provides stubs for the following methods:

   open
	 $conn = X11::Protocol::Connection::Foo->open($host, $display_num)

       Open a connection to the specified display (numbered from 0) on the specified $host.

   give
	 $conn->give($data)

       Send the given data to the server. Normally, this method is used only by the protocol module itself.

   get
	 $data = $conn->get($n)

       Read $n bytes of data from the server. Normally, this method is used only by the protocol module itself.

   fh
	 $filehandle = $conn->fh

       Return an object suitable for use as a filehandle. This is mainly useful for doing select() and other such system calls.

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.
