GetAs()

template<typename S >

std::vector< S * > JDatabundle::GetAs

(

)

Generically access the encapsulated data, performing an upcast if necessary.

This is useful for extracting data from all JFactories<T> where T extends a parent class S, such as JObject or TObject, in contexts where T is not known or it would introduce an unwanted coupling. The main application is for building DSTs.

Be aware of the following caveats:

• The factory's object type must not use virtual inheritance.
• If JFactory::Process hasn't already been called, this will return an empty vector. This will NOT call JFactory::Process.
• Someone must call JFactoryT<T>::EnableGetAs<S>, preferably the constructor. Otherwise, this will return an empty vector.
• If S isn't a base class of T, this will return an empty vector.
