Detailed Description

template<typename FactoryProduct>
class OpenMS::Factory< FactoryProduct >

Returns FactoryProduct* based on the name of the desired concrete FactoryProduct.

Every factory product base class T has to implement the static function registerChildren that registers all classes S derived from T at Factory<T>.

Every class S derived from T has to implement the function "static T* create()" which is going to be registered at Factory<T>. Additionally the function "static String getProductName()" is required, which returns the name the class is registered by.
