Description
This is the base class for all services registered with the ServiceRegistry.
All subclasses of Service must override the type() and isA() member functions.

Member Functions
isA
virtual bool isA(
const std::type_info & otherType
) const;
Returns true if the class is a subclass of the class given by type. Comparison must always be done by type name, not by simply comparing std::type_info object references.
Subclasses must override this member function.
The implementation of isA() is always as follows:
bool MyService::isA(const std::type_info& otherType) const
{
std::string name(typeid(MyService).name());
return name == otherType.name() || MyBaseClass::isA(otherType);
}
type
virtual const std::type_info & type() const;
Returns the type information for the object's class.
Subclasses must override this member function.
The implementation of isA() is usually as follows:
const std::type_info& MyService::type() const
{
return typeid(MyService);
}
If a service class implements a service interface, the type information for the interface class should be returned instead:
const std::type_info& MyServiceImpl::type() const
{
return typeid(MyService);
}
