Detailed Description

Declarative descriptors for selecting which particle PAYLOAD columns are written to H5Part (visualization) files. A ParticleTraits specialization may declare an optional h5PartColumns tuple of these descriptors; DischargeIO::writeH5Part then derives the output datasets directly, eliminating hand-maintained, positionally coupled name/accessor lists.

Position, id and weight are written automatically by writeH5Part and need NOT be listed here; only the EXTRA payload columns are. Each descriptor pairs a dataset name with the pointer(s)-to-member that select the column(s):

static constexpr auto h5PartColumns = std::make_tuple(
  H5Part::Scalar{"mobility", &ItoParticle::mobility},
  H5Part::Vector{"v", D_DECL(&ItoParticle::vx, &ItoParticle::vy, &ItoParticle::vz)});

Note

The descriptors live in a nested H5Part namespace so that H5Part::Vector does not collide with Chombo's Vector container.

Function Documentation

Scalar()

template<typename M >

H5Part::Scalar	(	const char *	,
		M
	)		-> Scalar< M >

Deduction guide so that Scalar{"name", &P::m} deduces the member-pointer type.

Template Parameters

M	Pointer-to-member type.

Vector()

template<typename... Ms>

H5Part::Vector	(	const char *	,
		Ms...
	)		-> Vector< Ms... >

Deduction guide so that Vector{"name", D_DECL(&P::x, &P::y, &P::z)} deduces the member-pointer types.

Template Parameters

Ms	Pointer-to-member types.
