Namespaces
namespace	Cantera
	Namespace for the Cantera kernel.

Macros
#define	CT_DEFINE_HAS_MEMBER(detector_name, func_name)
	A macro for generating member function detectors, which can then be used in combination with if constexpr to condition behavior on the availability of that member function.

Functions

template<class InputIter , class InputIter2 >
double	dot (InputIter x_begin, InputIter x_end, InputIter2 y_begin)
	Function that calculates a templated inner product.
template<class InputIter , class OutputIter , class S >
void	scale (InputIter begin, InputIter end, OutputIter out, S scale_factor)
	Multiply elements of an array by a scale factor.

void	checkFinite (const double tmp)
	Check to see that a number is finite (not NaN, +Inf or -Inf)
void	checkFinite (const string &name, double *values, size_t N)
	Check to see that all elements in an array are finite.
template<class T , class U >
const U &	getValue (const map< T, U > &m, const T &key, const U &default_val)
	Const accessor for a value in a map.

	Get the size of a container, cast to a signed integer type.

Macro Definition Documentation

CT_DEFINE_HAS_MEMBER

#define CT_DEFINE_HAS_MEMBER	(		detector_name,
			func_name
	)

Value:

    template<class T, class=void> \
    struct detector_name : std::false_type {}; \
    template<class T> \
    struct detector_name<T, std::void_t<decltype(&T::func_name)>> : std::true_type {};

A macro for generating member function detectors, which can then be used in combination with if constexpr to condition behavior on the availability of that member function.

See MultiRate for examples of use.
