operator>>() [1/2]

template<std::size_t NDIMS>

std::istream& operator>>	(	std::istream &	in,
		MercuryParticle< NDIMS > &	part
	)

Read a single particle from a istream.

{
  std::size_t i;
  for (i = 0; i < NDIMS; i++)
    in >> part.position[i];
  
  for (i = 0; i < NDIMS; i++) {
    in >> part.velocity[i];
    // convert velocities to float, because paraview cannot handle doubles
    part.velocity[i] = (float)part.velocity[i];
  }
 
  in >> part.radius;
  
  for (i = 0; i < NDIMS; i++)
    in >> part.rotation[i];
 
  for (i = 0; i < NDIMS; i++) {
    in >> part.angularV[i];
    // convert velocities to float, because paraview cannot handle doubles
    part.angularV[i] = (float)part.angularV[i];
  }
 
  in >> part.speciesID;
  
  return in;
}

operator>>() [2/2]

template<std::size_t NDIMS>

std::istream& operator>>	(	std::istream &	in,
		MercuryTimeStep< NDIMS > &	step
	)

Reads the time step header into the ts

Parameters

[in,out]	in	The istream where we read from
[out]	step	The timestream read into

Returns

in for chaining.

{
  std::size_t i;
  in >> step.numParticles_ >> step.time_;
  
  for (i = 0; i < NDIMS; i++)
    in >> step.min_[i];
    
  for (i = 0; i < NDIMS; i++)
    in >> step.max_[i];
 
  return in;
}
