Class AudioFileReader


  • public abstract class AudioFileReader
    extends Object
    Provider for audio file reading services. Classes providing concrete implementations can parse the format information from one or more types of audio file, and can produce audio input streams from files of these types.

      • 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

      • 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)

                                                           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

                                                             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
