Package Summary  Overview Summary

class:AudioFileReader [NONE]


  • 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.
    Since:
    1.3

constructor:<init>() [NONE]

  • AudioFileReader

    public AudioFileReader()

method:getAudioFileFormat(java.io.InputStream) [NONE]

  • 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 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
    NullPointerException - if stream is null
    See Also:
    InputStream.markSupported(), InputStream.mark(int)

method:getAudioFileFormat(java.net.URL) [NONE]

method:getAudioFileFormat(java.io.File) [NONE]

method:getAudioInputStream(java.io.InputStream) [NONE]

  • 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 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
    NullPointerException - if stream is null
    See Also:
    InputStream.markSupported(), InputStream.mark(int)

method:getAudioInputStream(java.net.URL) [NONE]

  • getAudioInputStream

    public abstract AudioInputStream getAudioInputStream​(URL url)
                                                  throws UnsupportedAudioFileException,
                                                         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
    NullPointerException - if url is null

method:getAudioInputStream(java.io.File) [NONE]

  • getAudioInputStream

    public abstract AudioInputStream getAudioInputStream​(File file)
                                                  throws UnsupportedAudioFileException,
                                                         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
    Throws:
    UnsupportedAudioFileException - if the File does not point to valid audio file data recognized by the system
    IOException - if an I/O exception occurs
    NullPointerException - if file is null
