Detailed Description

template<typename Cont, typename Enable = void>
struct phot::LibraryDataValidatorStruct< Cont, Enable >

Trait for determining the validity of library data in a container.

Template Parameters

Cont	type of container being tested
Enable	dummy type for std::enable_if_t hooks

This class is expected to be specialized to provide specific behavior for custom classes. The required interface consists of the single static method:

• static bool isValid(Cont const&) returning whether cont is valid

For example:

template <typename T, std::size_t N>
struct MyArray;

template <typename T, std::size_t N>
struct LibraryDataValidatorStruct<MyArray<T, N>, void> {
  static bool isValid(Cont const&) { return N > 0U; }
};

or

template <typename T>
struct MyVector;

template <typename T>
struct LibraryDataValidatorStruct
  <T, std::enable_if_t<util::is_instance_of<MyVector, T>>>
{
  static bool isValid(Cont const& cont) { return !cont.isInvalid(); }
};
