fa225846af new Temporal API to allow keeping MIDI notes in position after a map-tempo operation 2023-08-02 14:11:06 -06:00

c31c1906f7 temporal: fix dangling confusion about "omega"
Remove all reference to "omega_sc" and rename "omega_beats" as omega

ea2d2b4760 temporal: rename ::get_grid_with_iterator()
Because I like polymorphism

422fa7255b temporal: further extensions to GridIterator API to handle bar_mod/beat_div parameters
Also try to comment class definition to add a little clarity

cbaa335946 temporal: some cleanup of the GridIterator API 2023-07-14 21:32:40 -06:00
509efdb290 temporal: refactor ::get_grid() for performance reasons
the API now provides the option to call ::get_grid() with an iterator which may
be re-used on subsequent calls. This avoids unbounded O(N) "walks" from the
marker preceding the start point of the grid to the start point.

This commit also includes "fast-path" code for the common case of a single
tempo and single meter

81384537ef temporal: remove useless _floating member and API from TempoMapPoint 2023-07-14 13:03:36 -06:00
039f2d5d0e remove TempoMap::count_bars()
It's the only place in libtemporal that would require
a TempoMapPoints allocation, and there's no reason to do
this inside the library.

52f1b88749 temporal: remove ill-conceived lookup tables from tempo map (never publically visible)
These were not thread safe, and could not be: to be useful, a thread looking up a time
conversion could cache the result, but it would be using the global (shared) copy
of the map (because lookup is read-only, and so no write-copy is required). But
inserting into the lookup table wasn't lock protected (and shouldn't be because otherwise
that defeats the point of RCU).

So just drop it.
