Detailed Description

The abstract BootloaderBase class provides a basic bootstrapping sequence and hooks that specific implementations can override.

This class must be overridden to provide application specific boot loading sequence. It is just a template of the carousel's booting steps, so it contains empty realizations of all configure<> methods and instantiates default objects for the all create<> methods. You can derived from this class if you want determine your own bootloading sequence, but it is recomended to derived from the CarouselBootloader class and override create<> and configure<> methods and keep bootloading sequence.

Constructor & Destructor Documentation

BootloaderBase::BootloaderBase ( )

protected

Initializes a new instance of the BootloaderBase class.

When derive from this class you should override at least safeRun() method, in which loading sequence will be performed, and configureServiceLocator() method to register common services in the locator.

Member Function Documentation

void BootloaderBase::run ( )

virtual

Runs the bootloading process.

Implements IBootloader.

IServiceLocator* BootloaderBase::serviceLocator ( ) const

virtual

Gets the service locator, which should contains base objects after bootloading.

Implements IBootloader.

virtual void BootloaderBase::configureComponentManager ( )

protectedvirtual

Does nothing by default. When overridden in derived classes should add all components registered in provider to the component manager.

Reimplemented in CarouselBootloader.

virtual void BootloaderBase::configureComponentProvider ( )

protectedvirtual

Does nothing by default. You should override this method in the your specified bootloader to register new components, or setup components' discovering path (if you use DirectoryComponentProvider).

virtual void BootloaderBase::configureServiceLocator ( )

protectedpure virtual

When overridden in derived classes registers all common services such as IComponentManager, IComponentProvider and other in the locator.

Implemented in CarouselBootloader.

virtual IComponentManager* BootloaderBase::createComponentManager ( )

protectedvirtual

Creates default component manager using IComponentManager class and takes ownership.

virtual IComponentProvider* BootloaderBase::createComponentProvider ( )

protectedvirtual

Creates default provider using ComponentProvider class and takes ownership.

virtual LoggerFacade* BootloaderBase::createLoggerEngine ( )

protectedvirtual

Creates default logger using TextLogger class with stdout output and takes ownership of this logger. Should be overridden in the derived classes to instantiate your own logger facade over the better logging system (e.g. log4cplus).

virtual IServiceLocator* BootloaderBase::createServiceLocator ( )

protectedvirtual

Creates default service locator using ServiceLocator class and takes ownership.

virtual QMainWindow* BootloaderBase::createMainWindow ( )

protectedvirtual

Creates default main window class and takes ownership.

virtual void BootloaderBase::initialiseComponentProvider ( )

protectedvirtual

Does nothing by default. When overridden in derived classes should call IComponentProvider::initialize() method for the created component provider.

Reimplemented in CarouselBootloader.

virtual void BootloaderBase::safeRun ( )

protectedpure virtual

It is a safe part of the public run() method, that guaranted it would be called in derived class only once per instance.

Implemented in CarouselBootloader.
