Constructor & Destructor Documentation

PairGenerationTransformFunc()

PairGenerationTransformFunc::PairGenerationTransformFunc	(	BreitWheelerGeneratePairs const	generate_functor,
		const WarpXParIter &	a_pti,
		int	lev,
		int	ngE,
		amrex::FArrayBox const &	exfab,
		amrex::FArrayBox const &	eyfab,
		amrex::FArrayBox const &	ezfab,
		amrex::FArrayBox const &	bxfab,

		amrex::Array< amrex::Real, 3 >	v_galilean,
		int	a_offset = 0
	)

Constructor of the PairGenerationTransformFunc functor.

A BreitWheelerGeneratePairs functor is passed by value. However, it contains only few integer and real parameters and few pointers to the raw data of the lookup tables. Therefore, it should be rather lightweight to copy.

Parameters

[in]

generate_functor

functor to be called to determine the properties of the generated pairs

Member Function Documentation

operator()()

template<typename DstData , typename SrcData >

AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE void PairGenerationTransformFunc::operator() ( DstData &  dst1, DstData &  dst2, SrcData &  src, int const  i_src, int const  i_dst1, int const  i_dst2  ) const

inlinenoexcept

Functor call. It determines the properties of the generated pair and it sets to -1 the id of the source photon.

Parameters

[in,out]	dst1	target species 1 (either electrons or positrons)
[in,out]	dst2	target species 2 (either electrons or positrons)
[in]	src	source species (photons)
[in]	i_src	particle index of the source species
[in]	i_dst1	particle index of target species 1
[in]	i_dst2	particle index of target species 2
