setServices()

virtual void neo::cca::Component::setServices ( Services *  cc ) throw ( Exception )

pure virtual

The component's containing framework provides services through the Services interface.

The Component instance will be called first with some non-0 (non-null) Services object. In order to do anything substantial as a component, the component will need to keep a copy of this pointer.

If the cc passed on the first call to setServices is 0/null, the component is free to ignore it or to throw an exception.

The next time that setServices is called, the argument cc will be 0/null, and that is the signal that the component should shut itself down. Shutdown is: releasing used ports. unregistering uses ports. removing provided ports. deallocating any other resources that are not released by the destructor function.

A second call to setServices with a non-0 cc that is made before a shutdown call (0 cc) is received is a framework error. The component is free to ignore it or to throw an exception.
