Detailed Description

Helper class to collect (not only) PoolQuery results.

Note
Unfortunately PoolQuery::begin might throw. Exceptions are caught and the query is treated as empty.

PoolQueryResult maintains a set of sat::Solvable. You can add/remove solvables to/from the set defined by:

The class is a sat::SolvIterMixin, so you can iterate the result not just as sat::Solvable, but also as PoolItem or ui::Selectable.

* // Constructed from PoolItem iterator pair
* PoolQueryResult result( pool.byKindBegin<Package>(), pool.byKindEnd<Package>() );
* MIL << result.size() << endl;
*
* {
* // Removing a PoolQuery result
* PoolQuery q;
* q.addAttribute( sat::SolvAttr::name, "[a-zA-Z]*" );
* q.setMatchGlob();
* result -= q;
* MIL << result.size() << endl;
* }
* MIL << result << endl;
*
* // Removing a range of sat::Solvables
* sat::WhatProvides poviders( Capability("3ddiag") );
* result -= PoolQueryResult( poviders.begin(), poviders.end() );
*
* // packages not starting with a letter, except 3ddiag
* MIL << result << endl;
*
