		const PoolItem &	poolitem_r,
		const Dep &	poolitemdep_r,
		function< bool(const CapAndItem &)>	action_r
	)			[inline]

Find all items in a ResPool matched by a certain PoolItems dependency set.

Iterates poolitem_r->dep(poolitemdep_r) and invokes action_r on each item in pool_r, that provides a match.

 bool consume( const CapAndItem & cai_r );

 ResPool  _pool;
 PoolItem _pi;

 // Invoke consume on all PoolItems obsoleted by pi.
 forEachPoolItemMatchedBy( _pool, _pi, Dep::OBSOLETES, consume );

Note:

action_r is invoked for each matching Capability. So if the same PoolItem provides multiple matches, action_r refers to the same PoolItem multiple times. It may as well be that poolitem_r provides a matching Capability. Use OncePerPoolItem to compensate this if neccessary.
