Typedef Documentation

mp_flt

template<class AllList , class L >

using knp::meta::mp_flt = boost::mp11::mp_filter_q<boost::mp11::mp_bind_front<mp_neq, boost::mp11::mp_size<AllList>>, L>

List of types from the global type list that are used in the local type list.

Template Parameters

AllList	global list of types.
L	local list of types (subset of AllList).

Definition at line 54 of file stringify.h.

mp_neq

template<class T1 , class T2 >

using knp::meta::mp_neq = boost::mp11::mp_bool<T1::value != T2::value>

Template used to determine if two arbitrary types are not the same at the compile stage.

mp_neq takes the value of true if the types are not the same, otherwise mp_neq takes the value of false.

Template Parameters

T1	first arbitrary type to compare.
T2	second arbitrary type to compare.

Definition at line 46 of file stringify.h.

mp_supported_indexes

template<class AllList , class L >

using knp::meta::mp_supported_indexes

Initial value:

 
    mp_flt<AllList, boost::mp11::mp_transform_q<boost::mp11::mp_bind_front<boost::mp11::mp_find, AllList>, L>>

Index array for types from the global type list that are used in the local type list.

Template Parameters

AllList	global list of types.
L	local list of types (subset of AllList).

Definition at line 62 of file stringify.h.

Function Documentation

get_supported_type_indexes()

template<typename AllTypes , typename SupportedTypes >

std::vector< size_t > knp::meta::get_supported_type_indexes

(

)

Get supported type indexes.

Template Parameters

AllTypes	global list of types.
SupportedTypes	local list of types.

Returns

vector with indexes of supported types.

Definition at line 84 of file stringify.h.

get_supported_type_names()

template<typename AllTypes , typename SupportedTypes , typename NamesType >

std::vector< std::string > knp::meta::get_supported_type_names

(

const NamesType &

type_names

)

Get names of supported object types.

Parameters

type_names

container (usually a tuple) of type names.

Template Parameters

AllTypes	global list of types.
SupportedTypes	local list of types.
NamesType	container type (automatically derived from type_names if not specified).

Returns

vector of type names.

Definition at line 104 of file stringify.h.

load_from_container()

template<typename SupportedTypes , typename AllVariants , typename ToContainer >

void knp::meta::load_from_container	(	const std::vector< AllVariants > &	from_container,
		ToContainer &	to_container )

Load elements from one container of all variants to another container that contains a subset of all variants.

Template Parameters

SupportedTypes	subset of variants.
AllVariants	all supported variants.
ToContainer	target container.

Parameters

from_container	source container.
to_container	target container.

Definition at line 47 of file variant_helpers.h.

type_name()

template<class T >

std::string knp::meta::type_name

(

)

Return type of variable as a string.

See Stack overflow.

Template Parameters

T	type of variable.

Returns

name of a variable type.

Note

Use as type_name<decltype(variable)>().

Definition at line 47 of file specialization_helpers.h.

Variable Documentation

always_false_v

template<class >

bool knp::meta::always_false_v = false

inlineconstexpr

Template used to generate a fixed false value for static asserts.
