Configuration method interface.
The Processing base class forces all the concrete classes derived from it to implement this method, which must actually perform the specific configuration tasks.
Note that the user can not call this method directly. He will use Configure instead. The argument is expected to be an object of the necesary concrete configuration class.
Reference | to the configuration object. |
true if the processing object is left in a consistent state, and can be executed.
This | method must throw a bad_cast exception if the argument is not an object of the expected configuration class. |

This method is used to determine if a given processing can change its interface of ports/controls after its construction (i.e.
changing the name of ports in ConcreteConfigure). If a concrete processing can do this, it should reimplement the method returning true, in order to notify networks, graphical interfaces, etc.
