Essential Idioms

• Naming Conventions
  Applications on the Symbian platform use a standard set of conventions to name their classes, structs, variables, functions, macros, enumerations, and constants. This topic explains the meaning of these conventions.
• Layout conventions
  Symbian code is laid out in a standard way. This information is provided to help you to read Symbian code, even if you choose not to adopt the same layout yourself.
• Class types
  A description of the four main types of class in Symbian C++.
• C++ and machine architecture
  The C++ language, following its foundation in C, is close to the machine architecture. This allows applications to be implemented efficiently, but, especially for developers new to the language, presents some issues of which you need to be aware. This topic reviews the basic language features from this perspective, and discusses how the resulting issues are handled.
• Object Orientation Basics
• Object Lifetimes and Cleanup
• Multiple Inheritance and Interfaces
• Descriptors
• Thin Templates
• Code Efficiency
• Defensive Programming
• Static Data
• Frameworks, Libraries and DLLs
• UIDs
• Application Start-Up Time Optimization
  It is important that phone users do not have to wait long for applications to start. This document summarizes the techniques for optimizing application start-up time.
• Exporting and Importing Classes
• Symbian Platform Fundamentals Example Code
  This code demonstrates the fundamental Symbian platform classes and shows basic techniques that can be employed in developing Symbian platform applications.
