Detailed inspection of attribute matches within the current Solvable.

The matches_iterator visits all attribute matches within the current Solvable, providing a sat::LookupAttr::iterator pointing to attribute.

While a matches_iterator itself becomes invalid if the PoolQueryIterator is advanced, the sat::LookupAttr::iterator it pointed to stays valid, even after the query ended.

// Setup query for "libzypp" in name or requires:
PoolQuery q;
q.addString( "libzypp" );
q.setMatchSubstring();
q.setCaseSensitive( false );
q.addAttribute( sat::SolvAttr::name );
q.addDependency( sat::SolvAttr::requires );
// Iterate the result:
for_( solvIter, q.begin(), q.end() )
{
sat::Solvable solvable( *solvIter );
cout << "Found matches in " << solvable << endl;
if ( verbose )
for_( attrIter, solvIter.matchesBegin(), solvIter.matchesEnd() )
{
sat::LookupAttr::iterator attr( *attrIter );
cout << " " << attr.inSolvAttr() << "\t\"" << attr.asString() << "\"" << endl;

Detailed Description

PoolQuery iterator as returned by PoolQuery::begin.

The PoolQueryIterator visits sat::Solavables that do contain matches.

But it also provides an iterator by itself, to allow a detailed inspection of the individual attribute matches within the current Solvable.
