Include dependency graph for Utilities.hpp:

This graph shows which files directly or indirectly include this file:

Classes
struct	LLU::dependent_false< T >
	Get a type that inherits from false_type and ignores the template parameter completely. More...

struct	LLU::NumericArrayFromEnum< numericarray_data_t >
	Utility structure that matches an MNumericArray data type with corresponding C++ type. More...

Namespaces
	LLU
	Main namespace of LibraryLink Utilities.

	LLU::NA
	Small namespace for NumericArray related utilities.

Type aliases
template<typename T >
using	LLU::remove_cv_ref = std::remove_cv_t< std::remove_reference_t< T > >
	Utility type that strips any given type from reference and cv qualifiers. More...

template<typename A , typename B >
using	LLU::disable_if_same_or_derived = typename std::enable_if_t<!std::is_same< A, B >::value &&!std::is_base_of< A, remove_cv_ref< B > >::value >
	Utility type that is valid only if B is not A and not a subclass of A. More...

template<typename A , typename B >
using	LLU::enable_if_same_or_derived = typename std::enable_if_t< std::is_same< A, B >::value\|\|std::is_base_of< A, remove_cv_ref< B > >::value >
	Utility type that is valid only if B is A or a subclass of A. More...

template<typename Iterator >
using	LLU::enable_if_input_iterator = enable_if_same_or_derived< std::input_iterator_tag, typename std::iterator_traits< Iterator >::iterator_category >
	Utility type that checks if given type can be treated as input iterator. More...

template<typename Container >
using	LLU::enable_if_integral_elements = typename std::enable_if_t< std::is_integral< typename std::remove_reference_t< Container >::value_type >::value >
	Utility type that checks if given container type has elements that are integers (and therefore can be used as Tensor or NumericArray dimensions) More...

template<numericarray_data_t rat>
using	LLU::NumericArrayTypeFromEnum = typename NumericArrayFromEnum< rat >::type
	Simple type alias to easily extract type from NumericArrayFromEnum. More...

Enumerations
enum	LLU::NA::ConversionMethod { Check = MNumericArray_Convert_Check, ClipCheck = MNumericArray_Convert_Clip_Check, Coerce = MNumericArray_Convert_Coerce, ClipCoerce = MNumericArray_Convert_Clip_Coerce, Round = MNumericArray_Convert_Round, ClipRound = MNumericArray_Convert_Clip_Round, Scale = MNumericArray_Convert_Scale, ClipScale = MNumericArray_Convert_Clip_Scale }
	Possible methods of handling out-of-range data when converting a NumericArray to different type. More...

Functions
template<typename VariantType , typename T , std::size_t index = 0>
constexpr std::size_t	LLU::variant_index ()
	Get index of given type in the variant. More...

template<typename... Ts>
void	LLU::Unused (Ts &&...)
	Dummy function called on otherwise unused parameters to eliminate compiler warnings. More...

std::string	LLU::NA::typeToString (numericarray_data_t t)
	Get name of the given MNumericArray type, e.g. More...

Variables
template<typename Container >
constexpr bool	LLU::has_size_v = has_size<Container>::value
	A type trait to check whether type `Container` has a member function `size()` More...

template<typename Container , typename T >
constexpr bool	LLU::is_iterable_container_with_matching_type_v
	A type trait to check whether type `Container` is a class type with a member type alias `value_type` equal to T and with begin() and end() methods. More...

template<typename T >
constexpr bool	LLU::dependent_false_v = dependent_false<T>::value
	Compile-time boolean constant false that "depends" on a template parameter. More...

template<typename T >
constexpr imagedata_t	LLU::ImageType = MImage_Type_Undef
	Utility variable template that matches a C++ type with a corresponding MImage data type. More...

template<typename T >
constexpr numericarray_data_t	LLU::NumericArrayType = MNumericArray_Type_Undef
	Utility structure that matches a C++ type with a corresponding MNumericArray data type. More...

template<typename T >
constexpr mint	LLU::TensorType = MType_Undef
	Utility structure that matches a C++ type with a corresponding MTensor data type. More...
