Detailed Description

template<class Derived, class DerivedSolvable_iterator>
class zypp::sat::SolvIterMixin< Derived, DerivedSolvable_iterator >

Base class providing common iterator types based on a Solvable iterator.

A class deriving from SolvIterMixin must provide two methods begin and end returning iterator over sat::Solvable.

SolvIterMixin will then provide iterators over the corresponding PoolItem and ui::Selectable_Ptr.

SolvIterMixin will also provide default implementations for empty and size by iterating from begin to end. In case Derived is able to provide a more efficient implementation, the methods should be overloaded.

Note: You will sometimes face the problem, that when using the PoolItem iterator you hit multiple version of the same package, while when using the ui::Selectable iterator the information which of the available candidates actually matched got lost. In this case class PoolItemBest may help you. Use it to pick the best version only.
