moduleNetworking

The networking module contains classes for building client/server applications.

The most important features in this module is the remote object framework implemented by PiiRemoteObjectServer and PiiRemoteObjectClient. It provides a simple and easy-to-use HTTP-based alternative to QtDBus. The framework doesn't try to be universal and support any programming language (although JavaScript works). That said, the HTTP-based protocol is easy to implement and provides a natural interface to web applications, without the need for external daemons/services. Furthermore, the "native" Qt implementation has the advantage that no stub compilers or adaptors are needed.

The networking module also provides PiiNetworkServer, a generic multi-threaded server for network applications. It is used to implement a multi-threaded web server. HTTP clients and servers can be implemented easily with the aid of PiiHttpDevice. PiiMultipartDecoder makes it easy to parse multi-part MIME messages such as form submissions.
