* More generally, the term Factory Method is often used to refer to any method * whose main purpose is creation of objects.
*
* Wikipedia
* * Loki proposes a generic version of the Factory. Here is a typical use.
*
* 1. Factory< AbstractProduct, int > aFactory;
* 2. aFactory.Register( 1, createProductNull );
* 3. aFactory.CreateObject( 1 );
*

*
* - 1. The declaration
* You want a Factory that produces AbstractProduct.
* The client will refer to a creation method through an int.
* - 2.The registration
* The code that will contribute to the Factory will now need to declare its * ProductCreator by registering them into the Factory.
* A ProductCreator is a just a function that will return the right object. ie
* * Product* createProductNull()
* {
* return new Product
* }
*

* - 3. The use
* Now the client can create object by calling the Factory's CreateObject method * with the right identifier. If the ProductCreator were to have arguments * (ie :Product* createProductParm( int a, int b )) */ namespace Loki { /** * \defgroup FactoryErrorPoliciesGroup Factory Error Policies * \ingroup FactoryGroup * \brief Manages the "Unknown Type" error in an object factory * * \class DefaultFactoryError * \ingroup FactoryErrorPoliciesGroup * \brief Default policy that throws an exception * */ template struct DefaultFactoryError { struct Exception : public std::exception { const char* what() const throw() { return "Unknown Type";
