- inherit from std::iterator to obtain the full STL typedefs, meaning
that std::distance works and the following is now possible:
labelRange range(100, 1500);
scalarList list(range.begin(), range.end());
--
Note that this does not work (mismatched data-types):
scalarList list = identity(12345);
But this does, since the *iter promotes label to scalar:
labelList ident = identity(12345);
scalarList list(ident.begin(), ident.end());
It is however more than slightly wasteful to create a labelList
just for initializing a scalarList. An alternative could be a
a labelRange for the same purpose.
labelRange ident = labelRange::identity(12345);
scalarList list(ident.begin(), ident.end());
Or this
scalarList list
(
labelRange::null.begin(),
labelRange::identity(12345).end()
);
