  public MidiFileWriter()

Method Detail

• getMidiFileTypes

  public abstract int[] getMidiFileTypes()

  Obtains the set of MIDI file types for which file writing support is provided by this file writer.

  Returns:

  array of file types. If no file types are supported, an array of length 0 is returned.

• getMidiFileTypes

  public abstract int[] getMidiFileTypes(Sequence sequence)

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

  Parameters:

  sequence - the sequence for which MIDI file type support is queried

  Returns:

  array of file types. If no file types are supported, returns an array of length 0.

• isFileTypeSupported

  public boolean isFileTypeSupported(int fileType)

  Indicates whether file writing support for the specified MIDI file type is provided by this file writer.

  Parameters:

  fileType - the file type for which write capabilities are queried

  Returns:

  true if the file type is supported, otherwise false

• isFileTypeSupported

  public boolean isFileTypeSupported(int fileType,
                                     Sequence sequence)

  Indicates whether a MIDI file of the file type specified can be written from the sequence indicated.

  Parameters:

  fileType - the file type for which write capabilities are queried

  sequence - the sequence for which file writing support is queried

  Returns:

  true if the file type is supported for this sequence, otherwise false

• write

  public abstract int write(Sequence in,
                            int fileType,
                            OutputStream out)
                     throws IOException

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

  Parameters:

  in - sequence containing MIDI data to be written to the file

  fileType - type of the file to be written to the output stream

  out - stream to which the file data should be written

  Returns:

  the number of bytes written to the output stream

  Throws:

  IOException - if an I/O exception occurs

  IllegalArgumentException - if the file type is not supported by this file writer
