Java javax.sound.sampled.spi Class AudioFileWriter（JDK8）

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

• 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
