template<typename T, typename GetIterator>
auto	makeMemberRangeView (const ShadoweePtr< T > &self, GetIterator begin, GetIterator end)
	Returns a `MemberRangeView` iterating over `(self->begin)()` and `(self->end)()`

Detailed Description

template<typename SelfType, typename ValueType, typename GetIterator>
class lass::python::MemberRangeView< SelfType, ValueType, GetIterator >

View that adapts member iterator accessors to a PyIteratorRange.

MemberRangeView holds a ShadoweePtr to the container, and obtains the iterator pair by calling the supplied member accessors (self->*begin)() and (self->*end)() when iter() is invoked.

iter() produces a PyIteratorRange and sets self as its owner, keeping the container alive for the duration of the iteration.

The main benefit of returning a MemberRangeView over a plain PyIteratorRange is that it correctly types the iterator's value type in the generated Python stubs as ValueType, in contrast to the generic Any type used by PyIteratorRange.

Template Parameters

SelfType	C++ container type
ValueType	Element type returned by the container's iterators
GetIterator	Function type of the member iterator accessors.
