sequence)

Implements abstract javax.sound.midi.spi.MidiFileWriter.getMidiFileTypes.

Obtains the file types that this provider can write from the sequence specified.

private int
getType(int byteValue)

Returns ONE_BYTE, TWO_BYTE, SYSEX, META, ERROR, or IGNORE (i.e. invalid for a MIDI file)

public int
write(Sequence in, int type, OutputStream out)

Implements abstract javax.sound.midi.spi.MidiFileWriter.write.

Writes a stream of bytes representing a MIDI file of the file type indicated to the output stream provided.

public int
write(Sequence in, int type, File out)

Implements abstract javax.sound.midi.spi.MidiFileWriter.write.

Writes a stream of bytes representing a MIDI file of the file type indicated to the external file provided.
