we need an autodiff library at some point (or we need to roll our own but I do not think that makes sense). CppAD is well tested and header only and easy to include. It is also Liscene compatible with GPL v3.0. Here we bring it in as a dependency

$section The is_pod Template Function$$
|
|
|
|
$head Default Definition$$
|
|
The default template definition is that
|
|
$codei%
|
|
is_pod<%Type%>()
|
|
%$$
|
|
is false for all types.
|
|
|
|
$head Fundamental Types$$
|
|
This file specializes $codei%is_pod<%Type%>%$$ to be true where $icode Type$$
|
|
is any of the c++11 fundamental types that hold data; i.e.,
|
|
$code void$$ and $code nullptr_t$$ are excluded.
|
|
|
|
$head Other Type$$
|
|
You can inform CppAD that a particular $icode Type$$ is plain old data by
|
|
defining
|
|
$codei%
|
|
namespace CppAD { namespace local {
|
|
template <> inline bool is_pod<%Type%>(void) { return true; }
|
|
} }
