A temporal sample composed of a time-neutral field set. Time/index metadata belongs here; field conversion and payload storage belong to ExportFieldSet. The latter can also be owned directly by an exporter without constructing a Step or referencing a TimeSet. Step owns scheduling and publication policy. Field revisions invalidate the published state even when registration uses fieldSet() directly. Mutation is not thread-safe; owners must honor collective registration. More...

Detailed Description

template<typename MeshType, int N = 1>
class Feel::detail::TimeSet< MeshType, N >::Step

A temporal sample composed of a time-neutral field set. Time/index metadata belongs here; field conversion and payload storage belong to ExportFieldSet. The latter can also be owned directly by an exporter without constructing a Step or referencing a TimeSet. Step owns scheduling and publication policy. Field revisions invalidate the published state even when registration uses fieldSet() directly. Mutation is not thread-safe; owners must honor collective registration.
