TimeGrid Class Reference

#include "steam/asset/meta/time-grid.hpp"

Description

Interface: a grid and scale definition for time quantisation.

This meta-Asset describes a coordinate system or reference scale for quantised time values. Especially it allows to define an actual implementation, which can then implicitly be used by lib::time::QuTime and for conversions into timecode.

Note
for this to work, the actual implementation classes returned by the builder or the static build function additionally expose an implementation of the lib::time::Quantiser API
