the standard says (brackets mine) in cases listed in 3.4.1 [unqualified name lookup], scopes searched declaration in order listed in each of respective categories … why names kept in sort of ordered list(s)? after all, except function overloading , name hiding, think names unique within namespace. update address comment: i expect compiler keep names defined in container such unordered_set per scope , scopes linked in chain. i wondering why names classified lists per category (which thought variables, typedefs, structure like, functions, templates, etc.) , lists further sorted. the "order" in case not order of names . order of scopes . in each category scopes listed in order (typically "inside-out": inner scopes outer scopes). order in these scopes searched. typically, first scope contains name in question causes search stop.

i want use realm replace sqlite in android store list of classes, code simple below. public class myrealmobject extends realmobject { public string getfield() { return field; } public void setfield(string field) { this.field = field; } private string field; ... } list<myobject> myobjects = new arraylist(); realm realm = realm.getinstance(this); for(myrealmobject realm : realm.allobjects(myrealmobject.class)) { myobjects.add(new myobject(realm)); } realm.close(); return myobjects; however, performance slower simple sqllite table on tested device, using wrong way? there optimization tricks? why want wrap realmobjects in myobject class?. copying entire result set means loose benefit of using realm, namely doesn't copy data unless needed to. realmresults implements list interface should able use 2 interchangeably. list<myrealmobject> myobjects; realm realm = realm.getinstance(this); myobjects = realm.

here input file: $ cat abc 0 1 2 3 4 5 why following give one-column output instead of two-column one? $ cat abc | awk '{ print $1==0?"000":"111" $1==0? "222":"333" }' 000 333 333 shouldn't output following? 000 222 111 333 111 333 i think awk going parse as: awk '{ print ($1==0) ? "000" : (("111" $1==0) ? "222" : "333") }' that is, when prints 3 zeros, doesn't consider rest of operation. , when doesn't print 3 zeros, prints triple threes because "111" concatenated string not going evaluate zero. you want use: awk '{ print ($1==0?"000":"111"), ($1==0? "222":"333") }' where comma puts space (ofs or output field separator, precise) in output between 2 strings. or might prefer: awk '{ print ($1==0?"000":"111") ($1==0? "222":"333") }'
