PLMD::wrapper Namespace Reference

We use a separate namespace here instead of hiding these classes in the Plumed class, because some of these structs might be specialized by the user. More...

Classes
struct	has_size_and_data
	Primary template, assumes T does not have both size() and data() methods. More...
struct	has_size_and_data< T, void_t< decltype(std::declval< T >().size()), decltype(std::declval< T >().data())> >
	Specialization for types T that do have both size() and data() methods. More...
struct	is_custom_array
	Primary template, assumes T is not a custom structure. More...
struct	is_custom_array< std::array< T, N > >
	Template specialization for std::array. More...
struct	is_custom_array< T[N]>
	Template specialization for C arrays. More...
struct	make_void
	This is to replace c++17 std::void_t. More...

template<typename T , typename std::enable_if< wrapper::is_custom_array< typename std::remove_reference< T >::type >::value, int >::type = 0>
std::size_t	custom_array_size ()
	Report the size of a custom_array. More...
template<>
std::size_t	size (const std::string &obj)
	Specialization for std::string, which returns size()+1, which includes the terminating null character. More...
template<typename T >

	Generic utility to retrieve the size of a container. More...

Detailed Description

We use a separate namespace here instead of hiding these classes in the Plumed class, because some of these structs might be specialized by the user.

Typedef Documentation

void_t

template<typename... Ts>

using PLMD::wrapper::void_t = typedef typename make_void<Ts...>::type

Function Documentation

custom_array_cast()

template<typename T , typename std::enable_if< wrapper::is_custom_array< typename std::remove_reference< T >::type >::value, int >::type = 0>

wrapper::is_custom_array<T>::value_type* PLMD::wrapper::custom_array_cast ( T *  val )

inline

Cast a pointer to a custom_array to a pointer of its value_type.

typename std::remove_reference<T>::type is needed because C arrays are passed by reference

custom_array_size()

template<typename T , typename std::enable_if< wrapper::is_custom_array< typename std::remove_reference< T >::type >::value, int >::type = 0>

std::size_t PLMD::wrapper::custom_array_size ( )

inline

Report the size of a custom_array.

typename std::remove_reference<T>::type is needed because C arrays are passed by reference

size() [1/2]

template<>

std::size_t PLMD::wrapper::size ( const std::string &  obj )

inline

Specialization for std::string, which returns size()+1, which includes the terminating null character.

size() [2/2]

template<typename T >

std::size_t PLMD::wrapper::size ( const T &  obj )

inline

Generic utility to retrieve the size of a container.
