This document provides an overview of the Feature Registry.

-
Purpose

The Feature Registry allows -users to query whether optional Symbian platform features (identified by 32-bit -unique identifiers), are supported on a device prior to using them, and to -request notification of run-time feature changes.

-
Architectural relationships

The main input to the -Feature Registry is a configuration file, which is created by the ROMBUILD tool. -This file defines a set of feature flags, which can be accessed using the -Feature Registry API.

The configuration file generated by the ROMBUILD tool -can be used to produce emulators specific to a particular ROM image using -the EMULATORBUILD tool. For more information, refer to the OS Customisation guide.

-
Description

The main purpose of the Feature Registry -is to provide a public API for querying whether managed Symbian platform features -are supported on a device.

Feature information is sourced from a configuration -file, which lists the status of features on the device. This configuration -file is created by the ROMBUILD tool.

A -notification API is also provided for future enhancements in which the Feature -Registry is able to be updated during run-time.

Features

A feature is a section of the Symbian platform API and its underlying -implementation, which accomplishes one or more useful tasks. Not all features -are supported on all Symbian platform devices. Some will be absent (unsupported) -because they are designated as optional features (sometimes referred to as -managed features) and device manufacturers have chosen not to include them -on a device. Others will be unavailable because they were added as part of -a later OS release or are UI-specific.

Feature Management

Feature Management is the overall -process, which controls how parts of Symbian platform are designated as features, -given unique identifiers and tracked for inclusion or exclusion during the -ROM-build process. The Feature Registry is an Application Programming Interface -(API) to the Feature Management process, permitting applications to find out -what features are available on the device at run-time. It is used by developers -to find out whether optional features are supported on the device, prior to -using them.
