Example 6 with StemDirection

use of com.xenoage.zong.core.music.chord.StemDirection in project Zong by Xenoage.

the class StemDirector method compute.

/**
 * Computes the {@link StemDirection} of the given chord (and maybe connected
 * ones) and returns them. The chord must be part of a score.
 */
public Map<Chord, StemDirection> compute(Chord chord) {
    Map<Chord, StemDirection> ret = map();
    Beam beam = chord.getBeam();
    Score score = chord.getScore();
    if (beam != null) {
        // compute stem directions for all chords of the beam
        StemDirection[] beamedStems = beamedStemDirector.compute(beam, score);
        for (int iChord : range(beam.size())) ret.put(beam.getChord(iChord), beamedStems[iChord]);
    } else {
        // compute stem direction for single chord
        MP mp = MP.getMP(chord);
        StemDirection stem = singleStemDirector.compute(chord, score.getMusicContext(mp, BeforeOrAt, Before));
        ret.put(chord, stem);
    }
    // but it was bad and outdated, so we removed it.
    return ret;
