System::Collections::Generic::ISet< T > Class Template Referenceabstract

Interface of collection containing a set of unique elements. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument. More...
