Detailed Description

The constant enumerator interface.

Enumerators allow to iterate throw the element of a collection. A constant enumerator could be used inside constant methods.

There is an example of utilisation: IConstEnumerator* enumerator = list.GetConstEnumerator(); while (enumerator->MoveNext()) {   IExportable* element = enumerator->GetCurrent();   ... }

Exception safety : No-throw guarantee. Implementations of this interface must never throws exceptions.

Member Function Documentation

virtual const IExportable* DriveEngine::IConstEnumerator::GetCurrent ( ) const

pure virtual

Gets the current element, if any.

Note that MoveNext sould be called once to gets the first element.

Exception safety : No-throw guarantee. This member function never throws exceptions.

Returns

The current element, if any. Otherwise, returns nullptr.

virtual bool DriveEngine::IConstEnumerator::MoveNext ( )

pure virtual

Move the iterator to the next element, if any.

Exception safety : No-throw guarantee. This member function never throws exceptions.

Returns

Returns true if there is a next element, false otherwise.

virtual void DriveEngine::IConstEnumerator::Reset ( )

pure virtual

Resets the enumerator.

Exception safety : No-throw guarantee. This member function never throws exceptions.
