Implements common code for various dictionary-alike data structures (e. g. Dictionary, SortedDictionary). Shouldn't be used directly, except for inheritance when defining containers. 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....operator= ( ICollection &&) Move assignment operator. ICollection & operator=...(const ICollection &) Move assignment operator. Object & operator=...
