Detailed Description

Functor invoking action_r on each matching Capability in a ResPool.

Functor is provided to ease using forEachMatchIn as action in other algorithms.

 bool consume( const CapAndItem & cai_r );

 ResPool  _pool;
 PoolItem _pi;

 // Invoke consume on all PoolItems obsoleted by pi.
 // short: forEachPoolItemMatchedBy( _pool, _pi, Dep::OBSOLETES, consume );
 for_each( _pi->dep(Dep::OBSOLETES).begin(),
           _pi->dep(Dep::OBSOLETES).end(),
           ForEachMatchInPool( _pool, Dep::PROVIDES, consume ) );

 // Invoke consume on all PoolItems obsoleting pi.
 // short: forEachPoolItemMatching( _pool, Dep::OBSOLETES, _pi, consume );
 for_each( pi->dep(Dep::PROVIDES).begin(),
           pi->dep(Dep::PROVIDES).end(),
           ForEachMatchInPool( _pool, Dep::OBSOLETES, consume ) );
