* @test verify the use of the MultiFact template to access Singletons.
|
|
* While generally speaking the MultiFact allows us to address
|
|
* and invoke several "production lines" by ID, an obvious
|
|
* use case would be to access a "family" of singletons
|
|
* through this mechanism. And indeed, \c MultiFact::Singleton
|
|
* is a preconfigured shortcut for this use case. The actual
|
|
* singleton access factories are placed into a static context
|
|
* (here in the anonymous namespace above) and their access
|
|
* operation is wired as "factory function".
|
|
* - we use a hierarchy of test dummy objects
|
|
* - we set up a singleton factory for several subclasses
|
|
* - the registration happens automatically in the ctor
|
|
* - we verify that we indeed get the correct flavour.
