/** \class ObjectFactory |

|
* \brief Create instances of a class. |
| 30 |
|
* |
| 31 |
|
* ObjectFactory is a helper class used to created instances of a |
| 32 |
|
* class. Object factories are used for instantiation because they allow |
| 33 |
|
* run-time replacement of a class with a user-supplied version. For |
| 34 |
|
* example, if you wished to replace an algorithm with your own custom |
| 35 |
|
* version, or with a hardware-accelerated version, ObjectFactory |
| 36 |
|
* can be used to do this. |
| 37 |
|
* |
| 38 |
|
* This implementation of the object factory is templated and uses RTTI |
| 39 |
|
* (Run-Time Type Information) to create the name of the class it is to |
| 40 |
|
* instantiate. (The name may include template type parameters, depending |
| 41 |
|
* on the class definition.) |
