C++ a class to be used only by another class -

-

i'm building class (class a) needs able create number of instances of class (class b) in course of operation, class b used few member functions of class a, , never used outside of class. how should class b best defined? practical / reasonable make private member of class a? intended purpose of nested classes, or parting spirit of construct?

thanks, wyatt

edit: on further consideration, i'm not asking best practice, personal project. want include class b member of class encapsulation standpoint - seems reasonable class wholly subordinate should in fact part of owning class.

what i'm wondering whether or not reasonable use-case nested classes? if not, purpose of nested classes?

one possibility define namespace called detail inside namespace put classes. e.g.

// public_namespace_detail.hpp namespace public_namespace {     namespace detail     {         class b         {           ...         };      } }  // public_namespace.hpp #include "public_namespace_detail.hpp"  namespace public_namespace {     class     {        detail::b b;        ...            }; }

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

-
i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
