Short introduction to Ardour classes

Short introduction to Ardour classes

Ardour's structure is object oriented. The main object is the Session. A Session contains Audio Tracks, Midi Tracks and Busses. Audio and Midi tracks are derived from a more general "Track" Object, which in turn is derived from a "Route" (aka Bus). @@ -672,10 +823,16 @@ Operations are performed on objects. One gets a reference to an object and then e.g obj = Session:route_by_name("Audio") obj:set_name("Guitar").

+Lua automatically follows C++ class inheritance. e.g one can directly call all SessionObject and Route methods on Track object. However lua does not automatically promote objects. A Route object which just happens to be a Track needs to be explicily cast to a Track. Methods for casts are provided with each class. Note that the cast may fail and return a nil reference. +

+

+Likewise multiple inheritance is a non-trivial issue in lua. To avoid performance penalties involved with lookups, explicit casts are required in this case. One example is which is-a StatefulDestructible which inhertis from both Stateful and Destructible. +

+

Object lifetimes are managed by the Session. Most Objects cannot be directly created, but one asks the Session to create or destroy them. This is mainly due to realtime constrains: you cannot simply remove a track that is currently processing audio. There are various factory methods for object creation or removal.
