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:

a single sat::Solvable
a single PoolItem
a PoolQuery
an other PoolQueryResult
any iterator pair with value_type sat::Solvable or PoolItem or PoolQuery or any type that fits operator+=.

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;
