Detailed Description

template<typename Vector>
struct lar::dump::VectorDumper< Vector >

Manipulator managing the dump of the vector content into a stream.

Template Parameters

Vector

the type of vector to be dumped

The manipulator is constructed with the object that needs to be dumped. This implementation requires a vector of at least 3D with methods X(), Y() and Z(). The dump is producer by the call operator, in the form

{ vx, vy, vz }

An overloaded insertion operator will call the operator() method of the manipulator to perform the insertion.

This class can be specialised to manage different vector types. For example:

#include <array>

namespace lar {
  namespace dump {

    // specialization for 3D std::array<>
    template <typename T>
    struct VectorDumper<std::array<T, 3U>> {

      using Vector_t = std::array<T, 3U>;

      Vector_t const& a;

      VectorDumper(Vector_t const& a): a(a) {}

      template <typename Stream>
      void operator() (Stream&& out) const
        { out << "{ " << a[0] << "; " << a[1] << "; " << a[2] << " }"; }

    }; // struct VectorDumper<array>


  } // namespace dump
} // namespace lar
