Class Voice

java.lang.Object

metdetection.voice.Voice

All Implemented Interfaces:

java.lang.Comparable<Voice>

public class Voice
extends java.lang.Object
implements java.lang.Comparable<Voice>

A Voice is a node in the LinkedList representing a voice. Each node has only a previous pointer and a MidiNote. Only a previous pointer is needed because we allow for Voices to split and clone themselves, keeping the beginning of their note sequences identical. This allows us to have multiple LinkedLists of notes without needing multiple full List objects. Rather, they all point back to their common prefix LinkedLists.
