  • Method Details

    • beforeParsingStarts

      public void beforeParsingStarts()
      Description copied from interface: ParserListener
      Called when the parser first starts up, but before it starts parsing anything. Provides listeners with a chance to initialize variables and get ready for the parser events.
      Specified by:
      beforeParsingStarts in interface ParserListener
    • afterParsingFinished

      public void afterParsingFinished()
      Description copied from interface: ParserListener
      Called when the parser has parsed its last item. Provides listeners with a chance to clean up.
      Specified by:
      afterParsingFinished in interface ParserListener
    • onTrackChanged

      public void onTrackChanged(byte track)
      Description copied from interface: ParserListener
      Called when the parser encounters a new track (also known as a channel; previously in JFugue, known as a Voice). Tracks correspond to MIDI tracks/channels.
      Specified by:
      onTrackChanged in interface ParserListener
      Parameters:
      track - the new track event that has been parsed
    • onLayerChanged

      public void onLayerChanged(byte layer)
      Description copied from interface: ParserListener
      Called when the parser encounters a new layer. A layer deals with polyphony within a track. While any track may have layers, layers are intended for use with the percussion track, where each layer may represent notes for a specific percussive instrument. Layers can essentially be thought of as a "track within a track." Each layer maintains its own time progression, so "L1 Eq Eq L2 Cq Gq" would be the same as saying "Eq+Cq Eq+Gq". Layers are a JFugue feature, and are not a part of the MIDI specification.

      onLayerChanged in interface ParserListener
    • onInstrumentParsed

      public void onInstrumentParsed(byte instrument)
      Description copied from interface: ParserListener
      Called when the parser encounters a new instrument selection.
      Specified by:
      onInstrumentParsed in interface ParserListener
      Parameters:
      instrument - the MIDI instrument value that has been parsed
    • onTempoChanged

      public void onTempoChanged(int tempoBPM)
      Description copied from interface: ParserListener
      Called when the parser encounters a new tempo selection.
      Specified by:
      onTempoChanged in interface ParserListener
      Parameters:
      tempoBPM - The new tempo value
    • onKeySignatureParsed

      public void onKeySignatureParsed(byte key, byte scale)
      Specified by:
      onKeySignatureParsed in interface ParserListener
    • onTimeSignatureParsed

      public void onTimeSignatureParsed(byte numerator, byte powerOfTwo)
      Description copied from interface: ParserListener
      The first parameter is the number of beats per measure; The second parameter is the power by which 2 must be raised to create the note that represents one beat. Example 1: For a 5/8 time signature, expect 5,3 (since 2^3 = 8) Example 2: For a 4/4 time signature, expect 4,2 (since 2^2 = 4)
      Specified by:
      onTimeSignatureParsed in interface ParserListener
    • onBarLineParsed

      public void onBarLineParsed(long id)
      Description copied from interface: ParserListener
      The separator character which indicates a bar line has been parsed. Generally, you will want to care about this if you're counting measures, but this should have no effect on the rendering of a parsed piece of music.
      Specified by:
      onBarLineParsed in interface ParserListener
      Parameters:
      id - This is the id of the measure, which is an optional numeric value following the bar character.
    • onTrackBeatTimeBookmarked

      public void onTrackBeatTimeBookmarked(String timeBookmarkId)
      Specified by:
      onTrackBeatTimeBookmarked in interface ParserListener
    • onTrackBeatTimeBookmarkRequested

      public void onTrackBeatTimeBookmarkRequested(String timeBookmarkId)
      Specified by:
      onTrackBeatTimeBookmarkRequested in interface ParserListener
    • onTrackBeatTimeRequested

      public void onTrackBeatTimeRequested(double time)
      Specified by:
      onTrackBeatTimeRequested in interface ParserListener
    • onPitchWheelParsed

      public void onPitchWheelParsed(byte lsb, byte msb)
      Specified by:
      onPitchWheelParsed in interface ParserListener
    • onChannelPressureParsed

      public void onChannelPressureParsed(byte pressure)
      Specified by:
      onChannelPressureParsed in interface ParserListener
    • onPolyphonicPressureParsed

      public void onPolyphonicPressureParsed(byte key, byte pressure)
      Specified by:
      onPolyphonicPressureParsed in interface ParserListener

      Specified by:
      onControllerEventParsed in interface ParserListener
    • onLyricParsed

      public void onLyricParsed(String lyric)
      Specified by:
      onLyricParsed in interface ParserListener
    • onMarkerParsed

      public void onMarkerParsed(String marker)

      onMarkerParsed in interface ParserListener
    • onFunctionParsed

      public void onFunctionParsed(String id, Object message)
      Specified by:
      onFunctionParsed in interface ParserListener
    • onNotePressed

      public void onNotePressed(Note note)
      Description copied from interface: ParserListener
      Used to indicate when a note is pressed. Used in realtime cases when notes are actually being pressed and released. Parsers that do not operate in realtime are not expected to report onNotePressed. Expect the Note event to contain only the note number and note-on velocity.
      Specified by:
      onNotePressed in interface ParserListener
    • onNoteReleased

      public void onNoteReleased(Note note)
      Description copied from interface: ParserListener
      Used to indicate when a note is released. Used in realtime cases when notes are actually being pressed and released. Parsers that do not operate in realtime are not expected to report onNoteReleased. Expect the Note event to contain only the note number and note-off velocity. Duration may not be set on the Note from onNoteReleased.
      Specified by:
      onNoteReleased in interface ParserListener
    • onNoteParsed

      public void onNoteParsed(Note note)
      Description copied from interface: ParserListener
      We may have actually parsed a musical note! In previous versions of JFugue, ParserListener had separate listeners for parallel notes and sequential notes (now termed harmonic and melodic notes, respectively) In this version of JFugue, whether a note is the first note, a harmonic note, or a melodic note is kept as a property on the Note object itself.
      Specified by:
      onNoteParsed in interface ParserListener
      Parameters:
      note - The note that was parsed. Please see the Note class for more details about notes!
