the use of the :: operator

[jimjim]

Hello All,

Assume:

class AnObjectType{
typedef std::list <AnotherObjectType> Collection;
typedef SmartIterator <Collection> Iterator;
Iterator get( void);
Collection mCollection;
}

AnObjectType::Iterator AnObjectType::get( ){ //does Iterator need to be
qualified (AnObjectType::) here, and why?
Collection::iterator scit ;
return AnObjectType::Iterator(mServiceCollection); //does Iterator need
to be qualified here, and why?
}

TIA

Yes, it does.
Collection::iterator scit ;
return AnObjectType::Iterator(mServiceCollection); //does Iterator
need to be qualified here, and why?
No, it does not.
}

The rest of the homework you need to do yourself. Find a good book
and read the explanation of the rules for "name lookup".
