Detailed Description

template<template< typename... > class ContainerType, template< typename... > class ParticleType, typename... Types>
struct amrex::DataLayoutPolicy< ContainerType, ParticleType< Types... >, DataLayout::SoA >

Implementation of the SoA policy. The underlying data structure is a Tuple<ContainerType<ParticleType>>. Note that unlike the AoS, this container works with a "ref_wrap"ed version of the particle data, so we can modify the particle data in the tile.
