Detailed Description

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.

Definition at line 54 of file YQPkgSelMapper.h.

Constructor & Destructor Documentation

◆ YQPkgSelMapper()

YQPkgSelMapper::YQPkgSelMapper ( )

Constructor.

Builds a cache, if necessary.

Definition at line 51 of file YQPkgSelMapper.cc.

Here is the call graph for this function:

◆ ~YQPkgSelMapper()

YQPkgSelMapper::~YQPkgSelMapper ( )
virtual

Destructor.

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

Definition at line 58 of file YQPkgSelMapper.cc.

Member Function Documentation

◆ findZyppSel()

ZyppSel YQPkgSelMapper::findZyppSel ( ZyppPkg  pkg)

Find the corresponding ZyppSel to a ZyppPkg.

Returns 0 if there is no corresponding ZyppSel.

Definition at line 108 of file YQPkgSelMapper.cc.

◆ rebuildCache()

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.
