Detailed Description

class to handle translation from D_TYPE to column position for flat data structures.

When the particle data is stored in a Nxm array, with N particles and m D_TYPES, this class provides a map between the column number and what data is in the column.

Member Data Documentation

int utilities::Data_map::data_layout_[D_SENTRY]

private

An array that serves as a look up table.

This takes advantage of the fact that enums resolve to integers, each entry is the location of the D_TYPE that resolves to that elements index. D_TYPES that aren't include are set to -1
