parameter_type
Header:
parameter_type.hAllows the method of passing a parameter to be determined by the type.
By default, if the type is fundamental or a pointer, then the parameter type is ‘by value’, otherwise ‘by const reference’.
template <typename T>
struct parameter_type;Defines
typeThe template may be specialised for specific types.
Example
class MyClass
{
};
template <>
struct parameter_type<MyClass>
{
// Pass Myclass by value.
typedef MyClass type;
};
template <typename T>
void Do_Stuff(typename etl::parameter_type<T>::type parameter)
{
}
// Pass by value.
int i = 1;
Do_Stuff(i);
// Pass by const reference.
etl::vector<int, 10> data;
Do_Stuff(data);
// Pass by value
MyClass myClass;
Do_Stuff(myClass);
