Hudební skladba - vstupy a výstupy - MIFI
Music Interchange File (MIF/MIFI)
Návrh formátu
Výměnný formát, tzv. "music interchange file" (MIF/MIFI), je nově definovaný formát XML souboru, který umožňuje definovat nejen existující (fixní) hudbu, ale také hudbu, která má být komponována.
Soubor (XML) je generován ze třídy MusicalBundle (list objektů typu MusicBlock).
public XElement GetXElement {
get {
XElement xbundle = new XElement(
"MIF",
new XAttribute("FileName", this.FileName));
XElement xcopyright = new XElement(
"Software",
new XAttribute("Name", MusicalSettings.ApplicationName),
new XAttribute("Www", MusicalSettings.ApplicationWeb));
xbundle.Add(xcopyright);
var xheading = this.FileHeading.GetXElement;
xbundle.Add(xheading);
//// Blocks
XElement xblocks = new XElement("Blocks");
foreach (MusicalBlock block in this.Blocks.Where(block => block != null)) {
var xblock = block.GetXElement;
xblocks.Add(xblock);
}
xbundle.Add(xblocks);
return xbundle;
}
}
