Detailed Description

template<typename T>
struct efl::eina::iterator< T >

C++ wrappers to the native Eina_Iterator.

It provides an OOP interface to the Eina_Iterator functions, and automatically take care of allocating a deallocating resources using the RAII programming idiom.

Member Typedef Documentation

template<typename T >
typedef base_type::value_type efl::eina::iterator< T >::value_type

Type for elements returned by the iterator.

template<typename T >
typedef base_type::pointer efl::eina::iterator< T >::pointer

Type for a pointer to an element.

template<typename T >
typedef base_type::reference efl::eina::iterator< T >::reference

Type for a reference to an element.

template<typename T >
typedef base_type::difference_type efl::eina::iterator< T >::difference_type

Type to represent the distance between two iterators.

Defines the iterator category as the same of the base class.

Constructor & Destructor Documentation

template<typename T >
efl::eina::iterator< T >::iterator ( Eina_Iterator iterator_ = 0)
inlineexplicit

Creates a iterator wrapping the given native Eina_Iterator handle.

This constructor creates an iterator that wraps the given native Eina_Iterator handle, providing an OOP interface to it.

Member Function Documentation

template<typename T >
self_type& efl::eina::iterator< T >::operator++ ( )
inline

Move the iterator to the next position.

Returns
The iterator itself.

This operator increments the iterator, making it point to the position right after the current one. At the end, it returns a reference to itself.

References eina_iterator_next().

template<typename T >
self_type& efl::eina::iterator< T >::operator++ ( int  )
inline

Move the iterator to the next position.

Returns
The iterator itself.

Works exactly like operator++().

template<typename T >
value_type& efl::eina::iterator< T >::operator* ( ) const
inline

Get a reference to the element currently pointed by the iterator.

Returns
Reference to the current element.
template<typename T >
pointer efl::eina::iterator< T >::operator-> ( ) const
inline

Return a pointer to the current element, which member will be accessed.

Returns
Pointer to the element currently pointed by the iterator.
