An iterable oject aggregates elements on which iteration is possible. iterable provides basic mechanisms to permorm this iteration. That is, it provides an iterable::iterator type, begin() / end() methods, and operator()().
In order to subclass iterable, you must define an iterator type for your iterable class. This type must have a similar constructor:
my_iterator::my_iterator(my_iterable& e, bool at_end);
The first argument refers to the object you want to iterate on. The second one indicates whether to point the iterator at the begining or past the end of this object's elements.
Once you defined this iterator type, just declare it as part of your iterable class' virtual types :
template <MyIterableParams> struct types< MyIterable<MyIterableParams> > { typedef my_iterator iterator; };
typedef HIDDEN tool::iterable< Bottom >::exact_type |
typedef HIDDEN tool::iterable< Bottom >::iterator |
Iterator type for this template instantiation.
iterable< B >::iterator tool::iterable< B >::begin | ( | ) | [inline] |
Get an iterator to the first element.
iterable< B >::iterator tool::iterable< B >::end | ( | ) | [inline] |
Get an iterator to the end (past the last element).
void tool::iterable< B >::operator() | ( | const O & | output | ) | [inline] |
Copy elements to output
.
