int QvecBase::SortCriterium = 3 [static]

sort criterium [0,1,2,3] = [px,py,pz,e] default is 3 = e.
this is used to define the sort criterium between 2 objects. Using this, AlephCollections can be sorted as a STL vector, just using sort. Be Carefull: sort will NOT work with collections of pointers. for that, you have to define some functor calling QvecBase::operator<
