Classes

class  Enumerator
 Enumerator class. 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...

Detailed Description

template<typename T>
class System::Collections::Generic::HashSet< T >

Forward declaration of HashSet class.

Set implementation based on hashing. 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.

Parameters
TElement type.
