Class AudioFileReader
- java.lang.Object
-
- javax.sound.sampled.spi.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.
- Since:

Methods
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
AudioFileFormatobject 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 - See Also:
-
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
AudioFileFormatobject 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- theFilefrom which file format information should be extracted - Returns:
- an
AudioFileFormatobject describing the audio file format - Throws:
-
UnsupportedAudioFileException- if theFiledoes 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 theAudioInputStreamshould be constructed - Returns:
- an
AudioInputStreamobject 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)
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 theAudioInputStreamshould be constructed - Returns:
- an
AudioInputStreamobject 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
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- theFilefor which theAudioInputStreamshould be constructed - Returns:
- an
AudioInputStreamobject based on the audio file data pointed to by the File - Throws:
-
UnsupportedAudioFileException- if theFiledoes not point to valid audio file data recognized by the system -
IOException- if an I/O exception occurs
