Description

template<class ISO>
class lib::iter_explorer::IterSourceIter< ISO >

Adapt an IterSource to make it iterable.

As such, lib::IterSource is meant to be iterable, while only exposing a conventional VTable-based iteration interface. To support this usage, the library offers some builders to attach an iterator adapter. Two flavours need to be distinguished:

• we get a reference to something living elsewhere; all we know is it's iterable.
• we get a pointer, indicating that we must take ownership and manage the lifetime. The iterable entity in this case can be assumed to be heap allocated, featuring a virtual destructor. The generated front-end has identical type in both cases; it is based on a shared_ptr, just a different deleter function is used in both cases. This design makes sense, since the protocol requires us to invoke virtual function IterSource::disconnect() when use count goes to zero.
