Detailed Description

template<typename SmartPointer, typename... ConstructorArguments>
class xentara::utils::core::Factory< SmartPointer, ConstructorArguments >

A factory for creating objects derived from of a certain base class.

Template Parameters

SmartPointer	The base class pointer used to manage the created object. Must be a unique_ptr or a shared_ptr to the base class object type.
ConstructorArguments	Arguments that will be passed to the objects' constructor when creating them. If SmartPointer is a unique_ptr, and the first argument is the corresponding deleter, or a reference to it, then that deleter will be passed to the constructor of unique_ptr instead of the object.
