Lightweight attribute value lookup.
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
Modifying the query will not affect any running iterator.
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 (
