eu.bandm.music.transform.MetricDurationSplitter_local

public class MetricDurationSplitter_local
extends Object

The task of splitting an (a) arbitrary rhythmic duration value into a sequence of durations which are a correct notation w.r.t (b) a currently ruling metrum, (c) a bar-relative start position, and (d) a certain notation style guideline, is a non-trivial task.

We call LOCAL those solutions which work on the informations (a) and (c) for only one event.
We call SEMI-GLOBAL those solutions which require all information for the WHOLE content of one single bar (=measure), i.e. which split a duration w.r.t. its context.
It is easy to show that local soulutions are not sufficient for the real practice, but for restricted cases. So we provide an implementation, as a start.

(A closely related problem is the determinatin of BEAM start and end points. On the conceptual level, this might be considered a second, immediately following transformation step. It may as well be formulated and implemented together with the splitting probĺem!)
