Summary

Common Design Patterns for Symbian OS is the first design patterns book that addresses Symbian OS specifically. It introduces programmers to the common design patterns that help implement a large variety of applications and services on Symbian OS. The goal of the book is to provide the experience of Symbian's developers to a wider audience and enable sophisticated programs to be quickly written and to a high standard. In order to do this, it: Provides patterns based on the Symbian OS architectural elements Describes how patterns suited for non-mobile software should be adapted or even avoided for Symbian OS Provides Symbian OS based examples and code illustrationsEach chapter covers patterns that address specific key concern experienced by developers: memory performance, time performance, power performance, security and responsiveness.This book is not specific to any particular version of Symbian OS. While individual examples may come from one version or another the patterns outlined in this book are intended to be more generic and based on the common functionality available in all releases. Where possible the examples given for the design patterns will directly reflect the software in Symbian OS.Common Design Patterns for Symbian OS is intended to be used in conjunction with one or more SDKs for specific Symbian OS phones and with the resources available at the Symbian DevNet web site. This facility will provide the background material needed to help understand the patterns and the examples accompanying them.
