Detailed Description

template<template< Ownership, MemSpace > class S, MemSpace M>
class celeritas::AuxStateData< S, M >

Helper class for retrieving templated state data on a single stream.

This class is most easily used with make_aux_state to create a "collection group"-style state (see Collection: a data portability class) associated with a AuxParamsInterface subclass.

The state class S must have a resize method that's constructable with an optional templated params data class P, a stream ID, and a state size.

The make_aux_state helper functions can be used to construct this class:

return make_aux_state<FooStateData>(*this, memspace, stream, size);

size_type size() const

Number of elements in the state.

Definition AuxStateData.hh:62

or

return make_aux_state<BarStateData>(memspace, stream, size);
