Detailed Description

template<class Base>
class canvas::DisambiguationHelper< Base >

Base class, initializing its own baseclass with m_aMutex.

This is necessary to make the CanvasBase, GraphicDeviceBase, etc. classes freely combinable - letting them perform this initialization would prohibit deriving e.g. CanvasBase from GraphicDeviceBase.

On top of that, disambiguates XEventListener::disposing and WeakComponentImplHelper::disposing.

Having two virtual methods with the same name, and not overriding them in every derived class, will hide one of them. Later trying to override the same method, will generate a new vtable slot, and lead to very hard to spot errors.

DisambiguationHelper()

template<class Base >

canvas::DisambiguationHelper< Base >::DisambiguationHelper ( )

inlineprotected

Construct DisambiguationHelper.

This method is the whole purpose of this template: initializing a base class with the provided m_aMutex member (the WeakComponentImplHelper templates need that, as they require the lifetime of the mutex to extend theirs).
