Class Overview

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.

Public Methods

public abstract AudioFileFormat getAudioFileFormat (InputStream stream)

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

public abstract AudioFileFormat getAudioFileFormat (URL url)

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

public abstract AudioFileFormat getAudioFileFormat (File file)

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

public abstract AudioInputStream getAudioInputStream (InputStream stream)

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

public abstract AudioInputStream getAudioInputStream (File file)

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

public abstract AudioInputStream getAudioInputStream (URL url)

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
