Search for an attribute in Pool, one Repository or one Solvable. LookupAttr builds the query, LookupAttr::iterator iterates over the result.
Per default LookupAttr looks for attributes associated with a Solvable. But you may also pass REPO_ATTR as Location argument, to lookup attributes associated with the Repository (e.g. DeltaRpm information).
For convenience
Use SolvAttr::allAttr to search all attributes.
To search for attributes located in a sub-structure (flexarray) you also have to pass the sub-structures attribute as parent. Passing SolvAttr::allAttr a parent will lookup the attribute in any
sub-structure. Few attributes are known to have a parent (
// Lookup all 'name' attributes: sat::LookupAttr q( sat::SolvAttr::name ); // Lookup all 'name' attributes within a sub-structure 'data': sat::LookupAttr q( sat::SolvAttr::name, sat::SolvAttr::data ); // Lookup all 'name' attributes within any sub-structure: sat::LookupAttr q( sat::SolvAttr::name, sat::SolvAttr::allAttr );
// look for all attributes of one solvable void ditest( sat::Solvable slv_r ) { sat::LookupAttr q( sat::SolvAttr::allAttr, slv_r ); MIL << q << ": " << endl; for_( it, q.begin(), q.end() ) { MIL << " " << it.inSolvAttr() << " = " << it.asString() << endl; } }
// look for an attribute in the pool. sat::LookupAttr q( sat::SolvAttr("susetags:datadir") ); MIL << q << ": " << endl; for_( it, q.begin(), q.end() ) { MIL << " " << it << endl; }
// look for a repo attribute in the pool. sat::LookupRepoAttr q( sat::SolvAttr::repositoryAddedFileProvides ); MIL << q << ": " << endl; for_( it, q.begin(), q.end() ) { MIL << " " << it << endl; }
