org.jjazz.rhythmmusicgeneration.api.GridChordContext

public class GridChordContext
extends Object

A helper class to calculate a number of data related to one chord symbol of a chord sequence with an associated grid.

Data covers the zone from the chord symbol before (or the start of chord sequence if no previous chord symbol) to the chord symbol after (or end of chord sequence if no next chord symbol). When present the bounding chord symbols before/after are not part of the covered zone.
