AddressExposingIter< IT > Class Template Reference

#include "lib/iter-adapter-ptr-deref.hpp"

Description

template<class IT>
class lib::AddressExposingIter< IT >

wrapper for an existing Iterator type to expose the address of each value yielded.

Typically this can be used to build visitation sequences based on values living within a stable data structure (e.g. unmodifiable STL vector)

Warning

use of this wrapper might lead to taking the address of temporaries. The continued existence of the exposed storage locations must be guaranteed.

Note

bool checkable if and only if source is...

reference operator* ( ) const

inline

Returns

address of the source iteraor's current result

Warning

exposing a reference to an internal pointer for sake of compatibility. Clients must not store that reference, but rather use it to initialise a copy. The internal pointer exposed here will be changed on increment.
