Detailed Description

template<typename T>
class pongasoft::Utils::Operators::Dereferenceable< T >

Implements all the various equality and relational operators for the type T which is assumed to encapsulate some value that can be accessed by dereferencing T or in other words T::operator*() returns the underlying value.

If T::operator*() returns a primitive, then it should just work and nothing else needs to be done.

If T::operator*() returns another class or struct, then the following operators should be defined (you can define only some of them depending on your use):

struct S {...};

struct T {
  constexpr S const & operator *() const {...}
};

// for equality and relational operations between 2 S
constexpr bool operator==(const S &lhs, const S &rhs) {...};
constexpr bool operator<(const S &lhs, const S &rhs) {...};

// for equality and relational operations between S and V
template<typename V>
constexpr bool operator==(const S &lhs, const V &rhs) {...};
template<typename V>
constexpr bool operator<(const S &lhs, const V &rhs) {...};

Note

This code is primarily used by the various XXParam classes which encapsulates some type.
