Factory

template <class AbstractClass> class Factory

@brief A factory for managing Karabo classes

The factory uses something like a hidden (private) Singleton-Pattern. This solves the problem of static initialization order but leaves a simple looking API to the user.

A single instance of a factory holds the function objects to all registered constructors. Constructors with zero or more parameters may be registered and directly called.

Functions

create	Create an Object of the class identified by factoryKey factoryKey : Return : a shared pointer to the created object
create	Create an Object of the class identified by factoryKey factoryKey : Return : a shared pointer to the created object cast to A1
getRegisteredClasses	Return the classIds registered in the factory Return :
has	Check if a class identified by factoryKey is known to the factory factoryKey : Return :
