Overview

Overview -

Purpose

The File Converter Framework converts data -from one format to another format. For example, HTML files can be converted -to Symbian word documents.

Architecture

The File Converter Framework -architecture provides a framework for ECOM plug-ins, called converters, that -can convert data between different formats. When an application requests to -convert data from one format to another format, the framework checks the list -of available converters. If there is a converter that can do the conversion, -then the framework assigns the request to that converter.

The following -diagram shows the File converter framework architecture.

API summary - - - -API -Description - - - - -

CCnaConverter

A class that contains the properties of a converter. These are a -UID and the data types that the converter supports.

- - -

CConverterBase

A class that provides an interface to access the converters.

- - -

CConverterBase2

A base class for converters.

- - -

CCnaConverterList

A class that provides a list of available converters. It allows -clients to search for and obtain converters for specific source and target -data types.

- - -

CCnaConvInfoFileReader2

A class that encapsulates a collection of converter properties, CCnaConverter, -read from a converter information .rsc file.

- - -

CMimeInfo

A class that contains the localized names for a data type.

- - -

MConverterUiObserver

An interface implemented by the client of a conversion operation -to observe conversion progress.

- - - -

Typical uses

Using a converter

File -Converter Framework provides APIs to list and search for converters. It also -provides an observer interface through which the progress and success or failure -of the conversion can be reported. For more information, see Using -a converter.

Writing a converter

File Converter -Framework specifies a plug-in interface for converters. For more information, -see Writing a Converter.
