I just added a class SolvIterMixin (zypp/sat/SolvIterMixin.h). Classes providing a sat::Solvable iterator - i.e methods begin() and end() returning an iterator pointing to sat::Solvable - may derive from it to add additional iterators. by now: // value_type sat::Solvable (the same as the derived class' begin/end) Solvable_iterator solvableBegin() const Solvable_iterator solvableEnd() const // value_type PoolItem PoolItem_iterator poolItemBegin() const PoolItem_iterator poolItemEnd() const // value_type ui::Selectable::Ptr Selectable_iterator selectableBegin() const Selectable_iterator selectableEnd() const (The Selectable_iterator will soon be enhanced to avoid multiple visits of the same Selectable, because multiple Solvables/PoolItems refer to the same Selectable.) The intention is that all classes providing a collection of solvables (Queries, Pattern/Patch contents, ...) offer this interface. To use SolvIterMixin derive from it and pass the class and the iterator type as template argument: * namespace detail * { * class WhatProvidesIterator; * } * * class WhatProvides * : public SolvIterMixin * { * public: * typedef detail::WhatProvidesIterator const_iterator; * * // Iterator pointing to the first Solvable. * const_iterator begin() const; * * // Iterator pointing behind the last Solvable. * const_iterator end() const; * * }; @PoolQuery: The Mixin requires begin/end being const methods, and the ResultIterator must be defined outside class PoolQuery. Once this is fixed, PoolQuery could add the SolvIterMixin interface. -- cu, Michael Andres +------------------------------------------------------------------+ Key fingerprint = 2DFA 5D73 18B1 E7EF A862 27AC 3FB8 9E3A 27C6 B0E4 +------------------------------------------------------------------+ Michael Andres YaST Development ma@novell.com SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg) Maxfeldstrasse 5, D-90409 Nuernberg, Germany, ++49 (0)911 - 740 53-0 +------------------------------------------------------------------+ -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org
