Detailed Description

The CompositeComponentProvider class provides access to members that control a collection of providers that behaves like a single provider.

You can use this class overriding the BootloaderBase::createComponentProvider() method in your bootloader. For example, if you want your application discovers system components from the nested "bin/" directory and custom user components from the "plugins/" it is a good idea to use CompositeComponentProvider class:

*   class MyBootloader : public CarouselBootloader
*   {
*   protected:
*      IComponentProvider *MyBootloader::createComponentProvider()
*      {
*          return new CompositeComponentProvider();
*      }
*      void MyBootloader::configureComponentProvider()
*      {
*          DirectoryComponentProvider *sysDir = new DirectoryComponentProvider("bin/");
*          (static_cast<CompositeComponentProvider *>(m_componentProvider))->addProvider(sysDir);
*
*          DirectoryComponentProvider *contribProvider = new DirectoryComponentProvider("plugins/");
*          (static_cast<CompositeComponentProvider *>(m_componentProvider))->addProvider(contribProvider);
*      }
*      // other customization
*      // ....
*   };
* 

The ComponentProvider also serves as a base class for more specialized Providers.

Note: it takes ownership for added providers, but not for components.

Constructor & Destructor Documentation

CompositeComponentProvider::CompositeComponentProvider ( QObject * parent = nullptr )

explicit

Initializes a new instance of the CompositeComponentProvider class and adds a default ComponentProvider to the providers list.

Member Function Documentation

CompositeComponentProvider& CompositeComponentProvider::addProvider ( IComponentProvider * provider )

Adds the provider to the list of providers. Also takes ownership for the provider.

QList<IComponent *> CompositeComponentProvider::components ( ) const

virtual

Gets the all components that are registered at the providers.

Implements IComponentProvider.

bool CompositeComponentProvider::initialize ( )

virtual

Initializes the all providers, which may load and validate the components.

Implements IComponentProvider.

bool CompositeComponentProvider::isInitialized ( ) const

virtual

Returns true, if provider alreadyinitialzied; otherwise, returns false.

Implements IComponentProvider.

void CompositeComponentProvider::registerComponent ( IComponent * component )

virtual

Registers the specified component at the default provider. Null pointers will be skipped.

Implements IComponentProvider.
