In theory, we could have provided CanvasHelper - and CanvasBase as a single template, but that would duplicate - a lot of code now residing in CanvasHelper only. - - This template basically interposes itself between the full - interface you implement (i.e. not restricted to XCanvas. The - problem with UNO partial interface implementation actually is, - that you cannot do it the plain way, since deriving from a - common base subclass always introduces the whole set of pure - virtuals, that your baseclass helper just overrided) and your - implementation class. You then only have to implement the - functionality <em>besides</em> XCanvas. - - <pre> - Example: - typedef ::cppu::WeakComponentImplHelper4< ::com::sun::star::rendering::XSpriteCanvas, - ::com::sun::star::lang::XInitialization, - ::com::sun::star::lang::XServiceInfo, - ::com::sun::star::lang::XServiceName > CanvasBase_Base; - typedef ::canvas::internal::CanvasBase< CanvasBase_Base, CanvasHelper > ExampleCanvas_Base; - - class ExampleCanvas : public ExampleCanvas_Base, - public SpriteSurface, - public RepaintTarget - { - }; - </pre> - - @tpl Base - Base class to use, most probably one of the - WeakComponentImplHelperN templates with the appropriate - interfaces. At least XCanvas should be among them (why else - would you use this template, then?). Base class must have an - Base( const Mutex& ) constructor (like the - WeakComponentImplHelperN templates have). As the very least, - the base class must be derived from uno::XInterface, as some - error reporting mechanisms rely on that. - - @tpl CanvasHelper - Canvas helper implementation for the backend in question. This - object will be held as a member of this template class, and - basically gets forwarded all XCanvas API calls. Furthermore, - everytime the canvas API semantically changes the content of - the canvas, CanvasHelper::modifying() will get called - (<em>before</em> the actual modification takes place). - - @tpl Mutex - Lock strategy to use. Defaults to using the - OBaseMutex-provided lock. Everytime one of the methods is - entered, an object of type Mutex is created with m_aMutex as - the sole parameter, and destroyed again when the method scope - is left. - - @tpl UnambiguousBase - Optional unambiguous base class for XInterface of Base. It's - sometimes necessary to specify this parameter, e.g. if Base - derives from multiple UNO interface (were each provides its - own version of XInterface, making the conversion ambiguous) - */ - template< class Base, - class CanvasHelper, - class Mutex=::osl::MutexGuard, - class UnambiguousBase=::com::sun::star::uno::XInterface > class CanvasBase : - public Base - { - public: - typedef Base BaseType;
