Manual Overview

---

This manual covers the Python wrappers around the OSE C++ class library. The wrappers make available functionality related to the logging system, the real time events system, the service agent framework for creating distributed applications, the HTTP servlet framework and the RPC over HTTP interfaces.

Python Modules	Lists the available Python modules and their purpose. Includes brief details regarding installation and setup of the users environment.
Logging Facility	Describes the message logging facility, including how to direct messages to a specific log channel, how to log messages to a file or to process them within the actual application.
Program Setup	Describes the interface to the configuration database, user environment and other process information.
Event Framework	Describes the interface to the event system, how to schedule jobs and setup callbacks in response to real time events such as timers, signals and socket activity.
Service Agents	Describes how to create service agents, add them to groups, subscribe to announcements regarding specific services or membership of specific service groups.
Service Reports	Describes how to subscribe to reports published by specific services. Ie., describes the publish/subscribe functionality provided by the service agent framework.
Service Requests	Describes how to send requests to remote or local service agents and how to handle any response or error which results. Ie., describes the messaging or request/reply functionality of the service agent framework.
Message Exchange	Describes how to connect up processes to form a distributed application, including a decentralised message exchange and exchange groups.
Message Encoding	Describes the Python types which can be used in messages and how this can be extended to incorporate new scalar data types.
Servlet Framework	Describes the HTTP daemon and servlet framework, including the predefined servlets and how to create customised HTTP server objects.
Servlet Objects	Describes how to create new servlet objects including how to handle forms, client congestion and delayed responses.
Servlet Plugins	Describes how to create servlet plugins and how to use the Python plugin to dynamically load servlets at runtime from the file system.
Remote Access	Describes the RPC over HTTP interfaces into the service agent framework, including support for NET-RPC, XML-RPC and SOAP protocols.
