Detailed Description

Store PoolQuery settings and assist PoolQueryIterator.

Basically the matcher performs a base query, which should preselect candidates for a match. And has some filter conditions on top of it. Query and fileter depend on the PoolQuery settings.

Matcher must be stateless, as it is shared between multiple PoolQueryIterator instances.

If base_iterator is at the end, advance moves it to the first match. Otherwise advance moves to the next match, or to the end, if there is no more match.

Note

The original implementation treated an empty search string as <it>"match always"</it>. We stay compatible.

Initialize a new base query.

bool zypp::detail::PoolQueryMatcher::isAMatch ( base_iterator &  base_r ) const

inlineprivate

Check whether we are on a match.

The check covers the whole Solvable, not just the current attribute base_r points to. If there's no match, also prepare base_r to advance appropriately. If there is a match, simply return true. advance always moves to the next Solvable if there was a match.

Note

: Caller asserts we're not at end.
