|
** Preconfigured adapters for some STL container standard usage situations.
|
||
|
|
** Especially, definitions for accessing views on common STL containers
|
||
|
|
** repackaged as <b>lumiera forward iterators</b>. Mostly the purpose
|
||
|
|
** is ease of use, we don't create an abstraction barrier or try to
|
||
|
|
** hide implementation details. (see iter-source.hpp for such an
|
||
|
|
** abstraction facility). As a benefit, these adapters can be
|
||
|
|
** considered low overhead.
