## javax.sound.sampled.spi
Class AudioFileWriter

    java.lang.Object
      javax.sound.sampled.spi.AudioFileWriter

    public abstract class AudioFileWriter

extends Object

Provider for audio file writing services. Classes providing concrete implementations can write one or more types of audio file from an audio stream.

Since:
  1.3

Constructor Summary
`AudioFileWriter()`

Method Summary
`abstract AudioFileFormat.Type[]` | `getAudioFileTypes()` Obtains the file types for which file writing support is provided by this audio file writer.
`abstract AudioFileFormat.Type[]` | `getAudioFileTypes(AudioInputStream stream)` Obtains the file types that this audio file writer can write from the audio input stream specified.
`boolean` | `isFileTypeSupported(AudioFileFormat.Type fileType)` Indicates whether file writing support for the specified file type is provided by this audio file writer.
`boolean` | `isFileTypeSupported(AudioFileFormat.Type fileType, AudioInputStream stream)` Indicates whether an audio file of the type specified can be written from the audio input stream indicated.
`abstract int` | `write(AudioInputStream stream, AudioFileFormat.Type fileType, File out)` Writes a stream of bytes representing an audio file of the file format indicated to the external file provided.
`abstract int` | `write(AudioInputStream stream, AudioFileFormat.Type fileType, OutputStream out)` Writes a stream of bytes representing an audio file of the file type indicated to the output stream provided.

Constructor Detail

### AudioFileWriter

    public AudioFileWriter()

Method Detail

### getAudioFileTypes

    public abstract AudioFileFormat.Type[] getAudioFileTypes()

  Obtains the file types for which file writing support is provided by this audio file writer.

  Returns:
    array of file types. If no file types are supported, an array of length 0 is returned.

### isFileTypeSupported

    public boolean isFileTypeSupported(AudioFileFormat.Type fileType)

  Indicates whether file writing support for the specified file type is provided by this audio file writer.

  Parameters:
    `fileType` - the file type for which write capabilities are queried
  Returns:
    `true` if the file type is supported, otherwise `false`

### getAudioFileTypes

    public abstract AudioFileFormat.Type[] getAudioFileTypes(AudioInputStream stream)

  Obtains the file types that this audio file writer can write from the audio input stream specified.

  Parameters:
    `stream` - the audio input stream for which audio file type support is queried
  Returns:
    array of file types. If no file types are supported, an array of length 0 is returned.

### isFileTypeSupported

    public boolean isFileTypeSupported(AudioFileFormat.Type fileType,
                                       AudioInputStream stream)

  Indicates whether an audio file of the type specified can be written from the audio input stream indicated.

  Parameters:
    `fileType` - file type for which write capabilities are queried
    `stream` - for which file writing support is queried
  Returns:
    `true` if the file type is supported for this audio input stream, otherwise `false`

### write

    public abstract int write(AudioInputStream stream,
                              AudioFileFormat.Type fileType,
                              OutputStream out)
                       throws IOException

  Writes a stream of bytes representing an audio file of the file type indicated to the output stream provided. Some file types require that the length be written into the file header, and cannot be written from start to finish unless the length is known in advance. An attempt to write such a file type will fail with an IOException if the length in the audio file format is `AudioSystem.NOT_SPECIFIED`.

  Parameters:
    `stream` - the audio input stream containing audio data to be written to the output stream
    `fileType` - file type to be written to the output stream
    `out` - stream to which the file data should be written
  Returns:
    the number of bytes written to the output stream
  Throws:
    `IOException` - if an I/O exception occurs
    `IllegalArgumentException` - if the file type is not supported by the system
  See Also:
    `isFileTypeSupported(AudioFileFormat.Type, AudioInputStream)`, `getAudioFileTypes()`

### write

    public abstract int write(AudioInputStream stream,
                              AudioFileFormat.Type fileType,
                              File out)
                       throws IOException

  Writes a stream of bytes representing an audio file of the file format indicated to the external file provided.

  Parameters:
    `stream` - the audio input stream containing audio data to be written to the file
    `fileType` - file type to be written to the file
    `out` - external file to which the file data should be written
  Returns:
    the number of bytes written to the file
  Throws:
    `IOException` - if an I/O exception occurs
    `IllegalArgumentException` - if the file format is not supported by the system
  See Also:
    `isFileTypeSupported(javax.sound.sampled.AudioFileFormat.Type)`, `getAudioFileTypes()`
