Detailed Description

template<class T>
class System::Collections::ObjectModel::Collection< T >

Base type for generic collection. 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.

Template Parameters
TElement type.
