Factory (const Factory< Type > &) | |
A private copy constructor to prevent copying. |
The base class for singleton factory classes.
The factory maintains an instance of each type that can be produced by the factory. This instance is called the prototype. There are two requirements on the type that can be handled by the factory. First that it has a member function name()
that returns a std::string
for its name. The name does not have to be the class name. And second that it has a member function clone
() to make a copy of itself.
In most cases, a derived class of Factory need only supply the a way to initialize list of prototypes. Most of the implementation is in this template class.

void add | ( | Type * | obj | ) |
Type * create | ( | const std::string & | name | ) |
Creates a new object from a prototype named name.
If found, returns a new object by invoking the clone() member function of the prototype. If not found, throws a FactoryException object with the name not found.

Type * prototype | ( | const std::string & | name | ) | const |
Returns a pointer to a prototype with name name.
If a prototype with name doesn't exit, throws a FactoryException object with the name not found.
