Low Level Libraries and Frameworks Overview

The Low Level Libraries and Frameworks collection comprises various low-level system and application utilities, a generic usability library and an extensible plug-in framework.

Description

Low Level Libraries and Frameworks includes the following components:

Application Utilities: A collection of libraries that provide low-level system and application utility APIs. It includes the following libraries:
- Activity Manager
- Basic Application Framework Utilities (BAFL)
- Base Services Utility Library (BSUL)
- System Utilities
For more information about this component, see Application Utilities.
Generic Usability Library (EUserHL): For historic reasons Symbian C++ has non-standard idioms for writing memory efficient leave-safe code. This library provides support for alternative mechanisms which might be more familiar to Symbian Developers new to Symbian platform, and which require fewer lines of code. These include:
- Single phase construction
- Constructors which can leave
- Self managing variable length strings
- Managed pointers which do not require explicit deletion
- Cleaned up pointers which do not require explicit use of the CleanupStack API.
For more information about this component, see EUser High Level Library.
Plug-in Framework (ECom): Provides a generic and extensible plug-in framework with which abstract interfaces can be defined and their implementations identified, loaded and managed at run time. For more information, see Plug-in Framework. For more information, see Plug-in Framework.
