Detailed Description

template<typename T>
struct LeechCraft::Util::InstanceFunctor< boost::optional< T > >

Implementation of the Functor class for boost.optional.

The implementation applies the function to the contents of the boost.optional if it's not empty, otherwise it just leaves an empty boost.optional.

This is analogous to the Maybe type.

Template Parameters
TThe element type contained inside the boost.optional.
