Class MusicXmlParser


  • public final class MusicXmlParser
    extends Parser
    Parses a MusicXML file, and fires events for ParserListener interfaces when tokens are interpreted. The ParserListener does intelligent things with the resulting events, such as create music, draw sheet music, or transform the data. MusicXmlParser.parse can be called with a file name, File, InputStream, or Reader

      • parse

        public void parse()
        Parses a MusicXML file and fires events to subscribed ParserListener interfaces. As the file is parsed, events are sent to ParserListener interfaces, which are responsible for doing something interesting with the music data. the input is a XOM Document, which has been built previously
        Throws:
        java.lang.Exception - if there is an error parsing the pattern
      • BPMtoPPM

        public static int BPMtoPPM​(float bpm)
        converts beats per minute (BPM) to pulses per minute (PPM) assuming 240 pulses per second In MusicXML, BPM can be fractional, so BPMtoPPM takes a float argument
        Parameters:
        bpm -
        Returns:
        ppm
