Detailed Description
This class acts as a factory for QInstaller::AbstractArchive. You can register one or more archive handlers with this factory and create registered objects based on the file suffix.
This class follows the singleton design pattern. Only one instance of this class can be created and its reference can be fetched from the instance() method.
Depending of the configuration features set at build time, one of the following archive handlers is registered by default:
- Lib7z
- LibArchive
