Class of a selection statement.
A select statement can either contain
bool MySelect::operator()(IValueLocator* l) { float px, py, pz; if ( l->get("PX",px) && l->get("PY",py) && l->get("PZ",pz) ) { float mom = sqrt(px*px+py*py+pz*pz); return mom > 100.0 * GeV; } return false; }
if "true" is returned, the object will be loaded completely.
