Method Detail

• getAudioFileFormat

  public abstract AudioFileFormat getAudioFileFormat(InputStream stream)
                                              throws UnsupportedAudioFileException,
                                                     IOException

  Obtains the audio file format of the input stream provided. The stream must point to valid audio file data. In general, audio file readers may need to read some data from the stream before determining whether they support it. These parsers must be able to mark the stream, read enough data to determine whether they support the stream, and, if not, reset the stream's read pointer to its original position. If the input stream does not support this, this method may fail with an IOException.

  Parameters:

  stream - the input stream from which file format information should be extracted

  Returns:

  an AudioFileFormat object describing the audio file format

  Throws:

  UnsupportedAudioFileException - if the stream does not point to valid audio file data recognized by the system

  IOException - if an I/O exception occurs

  InputStream.markSupported(), InputStream.mark(int)

• getAudioFileFormat

  public abstract AudioFileFormat getAudioFileFormat(URL url)
                                              throws UnsupportedAudioFileException,
                                                     IOException

  Obtains the audio file format of the URL provided. The URL must point to valid audio file data.

  Parameters:

  url - the URL from which file format information should be extracted

  Returns:

  an AudioFileFormat object describing the audio file format

  Throws:

  UnsupportedAudioFileException - if the URL does not point to valid audio file data recognized by the system

  IOException - if an I/O exception occurs

• getAudioFileFormat

  public abstract AudioFileFormat getAudioFileFormat(File file)
                                              throws UnsupportedAudioFileException,
                                                     IOException

  Obtains the audio file format of the File provided. The File must point to valid audio file data.

  Parameters:

  file - the File from which file format information should be extracted

  Returns:

  an AudioFileFormat object describing the audio file format

  Throws:

  UnsupportedAudioFileException - if the File does not point to valid audio file data recognized by the system

  IOException - if an I/O exception occurs

• getAudioInputStream

  public abstract AudioInputStream getAudioInputStream(InputStream stream)
                                                throws UnsupportedAudioFileException,
                                                       IOException

  Obtains an audio input stream from the input stream provided. The stream must point to valid audio file data. In general, audio file readers may need to read some data from the stream before determining whether they support it. These parsers must be able to mark the stream, read enough data to determine whether they support the stream, and, if not, reset the stream's read pointer to its original position. If the input stream does not support this, this method may fail with an IOException.

  Parameters:

  stream - the input stream from which the AudioInputStream should be constructed

  Returns:

  an AudioInputStream object based on the audio file data contained in the input stream.

  Throws:

  UnsupportedAudioFileException - if the stream does not point to valid audio file data recognized by the system

  IOException - if an I/O exception occurs

  See Also:

  InputStream.markSupported(), InputStream.mark(int)

• getAudioInputStream

  public abstract AudioInputStream getAudioInputStream(URL url)

                                                       IOException

  Obtains an audio input stream from the URL provided. The URL must point to valid audio file data.

  Parameters:

  url - the URL for which the AudioInputStream should be constructed

  Returns:

  an AudioInputStream object based on the audio file data pointed to by the URL

  Throws:

  UnsupportedAudioFileException - if the URL does not point to valid audio file data recognized by the system

  IOException - if an I/O exception occurs

• getAudioInputStream

                                                       IOException

  Obtains an audio input stream from the File provided. The File must point to valid audio file data.

  Parameters:

  file - the File for which the AudioInputStream should be constructed

  Returns:

  an AudioInputStream object based on the audio file data pointed to by the File
