Complex Event Processing: IT Liberator or Over-Engineering Hell?

by Adrian Bridgwater, Dr. Dobbs Before getting down to technical details, I’d like to ask whether the future position of Complex Event Processing (CEP) tools and engines spells good news or bodes ill for our technology future. Specifically, I’d like to question whether CEP represents a highly agile customer-influenced IT delivery driver, or whether CEP [...]

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. AUTHORS
