Member Function Documentation

◆ FindPreferredPkg()

template<typename Str , typename Itr >

PkgIterator FindPreferredPkg ( bool const & PreferNonVirtual = true ) const

find the package with the "best" architecture

The best architecture is either the "native" or the first in the list of Architectures which is not an end-Pointer

Parameters

PreferNonVirtual tries to respond with a non-virtual package and only if this fails returns the best virtual package

◆ SimilarVer()

template<typename Str , typename Itr >

bool SimilarVer ( const VerIterator & B ) const

inline

compares two version and returns if they are similar

This method should be used to identify if two pseudo versions are referring to the same "real" version
