Constructor & Destructor Documentation

Empty()

template<class T >

template<class T >

Arp::Base::Core::Enumerator< T >::Empty< T >::Empty ( Empty< T > &&  arg )

inlinedefaultnoexcept

Move constructor.

Parameters

arg	The argument to move.

Member Function Documentation

GetCurrent()

template<class T >

template<class T >

T Arp::Base::Core::Enumerator< T >::Empty< T >::GetCurrent ( void  )

inlineoverridevirtual

Gets the element at the current position.

Returns

The element at the current position.

Depending on the template parameter type of this interface, a reference or even const reference might be returned.

Exceptions

InvalidOperationException

When GetCurrent() is called before MoveNext() or after MoveNext() has returned false once.

Implements Arp::Base::Core::IEnumerator< T >.

MoveNext()

template<class T >

bool Arp::Base::Core::Enumerator< T >::Empty< T >::MoveNext ( void  )

inlineoverridevirtual

Moves this enumerator to the next position.

Returns

false if the end of the container/collections/enumeration has reached, otherwise true.
