juce::TypeHelpers::ParameterType

struct juce::TypeHelpers::ParameterType

template<typename Type>
struct juce::TypeHelpers::ParameterType< Type >

The ParameterType struct is used to find the best type to use when passing some kind of object as a parameter.

Of course, this is only likely to be useful in certain esoteric template situations.

E.g. "myFunction (typename TypeHelpers::ParameterType<int>::type, typename TypeHelpers::ParameterType<MyObject>::type)" would evaluate to "myfunction (int, const MyObject&)", keeping any primitive types as pass-by-value, but passing objects as a const reference, to avoid copying.

juce::TypeHelpers::SmallestFloatType

struct juce::TypeHelpers::SmallestFloatType

template<typename Type>
struct juce::TypeHelpers::SmallestFloatType< Type >

These templates are designed to take a type, and if it's a double, they return a double type; for anything else, they return a float type.
