Mapping from ZyppPkg to the correspoinding ZyppSel.
All instances of this class share the same cache. The cache remains alive as long as any instance of this class exists.

Builds a cache, if necessary.

virtual |
Destructor.
Clears the cache if this was the last YQPkgSelMapper (i.e. if refCount() reaches 0)

ZyppSel YQPkgSelMapper::findZyppSel | ( | ZyppPkg | pkg | ) |
Find the corresponding ZyppSel to a ZyppPkg.
Returns 0 if there is no corresponding ZyppSel.
Definition at line 109 of file YQPkgSelMapper.cc.
void YQPkgSelMapper::rebuildCache | ( | ) |
Rebuild the shared cache.
This is expensive. Call this only when the ZyppPool has changed, i.e. after installation sources were added or removed.
Since the cache is shared, this affects all instances of this class.
