Detailed Description

template<typename T>
struct LC::Util::InstanceFunctor< T >

The Functor class is used for types that can be mapped over.

Minimal complete definition:

• Apply() function and FmapResult_t alias.

For a reference imolementation please see InstanceFunctor<boost::optional<T>>.

Template Parameters

T	The functor type instantiated with some concrete containee type.

FmapResult_t

template<typename T >

template<typename F >

using LC::Util::InstanceFunctor< T >::FmapResult_t = detail::ImplementationType

The type of the functor after its elements were mapped by the function F.

This type should correspond to the return type of the Apply() function when passed this functor and a function of type F.

Template Parameters

F	The type of the function to apply to the elements inside this functor.

UndefinedTag

template<typename T >

using LC::Util::InstanceFunctor< T >::UndefinedTag = void

Member Function Documentation

Apply()

template<typename T >

template<typename F >

static FmapResult_t<F> LC::Util::InstanceFunctor< T >::Apply ( const T &  functor, const F &  function  )

static

Applies the function to the each of the elements inside the functor.

Parameters

[in]	functor	The functor whose values are subject to function.
[in]	function	The function that should be applied to the values in the functor.

Returns

A functor of type FmapResult_t<F> where each element the result of applying the function to the corresponding element in the source functor.

Template Parameters

F	The type of the function to apply to the elements in the function.
