  1. The Joy of Dissecting Weave Dawn Finney

  2. Creating Useful SongNodes Introducing the SongNodes Creating the SongNodes Creating a List to Work With

  3. Coding the SongNodes Within the SongPhrase class: //code for a1 static public Phrase A1() { double[] phrasedata = {JMC.A1,JMC.EN,JMC.A1,JMC.EN,JMC.A1,JMC.EN,JMC.A1,JMC.EN}; Phrase myPhrase = new Phrase(); myPhrase.addNoteList(phrasedata); return myPhrase; } //code for dg5 static public Phrase DG5() { double[] phrasedata = {JMC.G5,JMC.EN,JMC.G5,JMC.EN,JMC.G5,JMC.EN,JMC.G5,JMC.DEN}; Phrase myPhrase = new Phrase(); myPhrase.addNoteList(phrasedata); return myPhrase; } //code for c2 static public Phrase C2() { double[] phrasedata = {JMC.C2,JMC.EN,JMC.C2,JMC.EN,JMC.C2,JMC.EN,JMC.C2,JMC.DEN}; Phrase myPhrase = new Phrase(); myPhrase.addNoteList(phrasedata); return myPhrase; }

  4. Introducing the SongNodes a1 dg5 c2 Distinct SongNodes will make it easier to see how weave works.

  5. Creating the SongNodes SongNode a1 = new SongNode(); a1.setPhrase(SongPhrase.A1()); SongNode dg5 = new SongNode(); dg5.setPhrase(SongPhrase.DG5()); SongNode c2 = new SongNode(); c2.setPhrase(SongPhrase.C2());

  6. Creating a List to Work With a1.repeatNextInserting(dg5, 5);

  7. Dissection Analyzing the Inputs Cases

  8. Analyzing the Inputs

  9. Case: skip amount = 0 a1.weave(c2, 2, 0);

  10. Case: skip amount = 1 a1.weave(c2, 2, 1); Surprisingly a1.weave(c2, 2, 0); or a1.weave(c2, 2, 1); will yield the same result.

  11. Case: skip amount >=2 a1.weave(c2, 2, 2); Weave actually works fairly normally with cases with the skip amount is greater 2

  12. Case: the list is too short a1.weave(c2, 2, 4); I do not think it is possible to draw any conclusions until we see another case.

  13. Case: the list is too short again a1.weave(c2, 2, 8); So when the list is too short to accommodate the amount we want to skip, it will do what it can (like in the previous case) and then insert the node at the end of list regardless of the amount we wanted to skip or the number of times we wanted to weave the node into the list.

  14. The Code import jm.music.data.*; import jm.JMC; import jm.util.*; import jm.music.tools.*; public class tester{ public static void main(String[]args){ SongNode a1 = new SongNode(); a1.setPhrase(SongPhrase.A1()); SongNode dg5 = new SongNode(); dg5.setPhrase(SongPhrase.DG5()); SongNode c2 = new SongNode(); c2.setPhrase(SongPhrase.C2()); a1.repeatNextInserting(dg5, 5); a1.showFromMeOn(JMC.PIANO); //show original list //case amount to skip = 0 a1.weave(c2, 2, 0); a1.showFromMeOn(JMC.PIANO); //case amount to skip = 1 a1.repeatNext(dg5, 5); //resets the list to the original a1.weave(c2, 2, 1); a1.showFromMeOn(JMC.PIANO); //case amount to skip >=2 a1.repeatNext(dg5, 5); a1.weave(c2, 2, 2); a1.showFromMeOn(JMC.PIANO); //case list is too short a1.repeatNext(dg5, 5); a1.weave(c2, 2, 4); a1.showFromMeOn(JMC.PIANO); //case list is too short again a1.repeatNext(dg5, 5); a1.weave(c2, 2, 8); a1.showFromMeOn(JMC.PIANO); }}
