Detailed Description

template<class T>
template<class T>
class Arp::Base::Core::Enumerator< T >::StackComposite< T >

Use this class to build a single enumerator by multiple other enumerators using a stack

The enumerator on the top of the stack is enumerated first. After it's MoveNext() returned false it is removed from the stack. On pushing a new enumerator the GetCurrent() refers to the newly pushed enumerator.

Constructor & Destructor Documentation

StackComposite()

template<class T >

template<class T >

Arp::Base::Core::Enumerator< T >::StackComposite< T >::StackComposite ( StackComposite< 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 >::StackComposite< 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 >.

GetSize()

template<class T >

template<class T >

size_t Arp::Base::Core::Enumerator< T >::StackComposite< T >::GetSize ( void  ) const

inline

Get the size of this stack.

Returns

The size of this stack.

MoveNext()

template<class T >

template<class T >

bool Arp::Base::Core::Enumerator< T >::StackComposite< 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.

operator=()

template<class T >

template<class T >

Enumerator< T >::StackComposite & Arp::Base::Core::Enumerator< T >::StackComposite< T >::operator= ( StackComposite< T > &&  arg )

inlinedefaultnoexcept

Move assignment operator.

Parameters

arg	The argument to move.

Returns

This instance as reference.

Push()

template<class T >

template<class T >

void Arp::Base::Core::Enumerator< T >::StackComposite< T >::Push ( typename IEnumerator< T >::Ptr  enumerator )

inline

Parameters

enumerator

The enumerator to add to this stack.
