Constructor Detail

• FormatConversionProvider

  public FormatConversionProvider()

Method Detail

• getSourceEncodings

  public abstract AudioFormat.Encoding[] getSourceEncodings()

  Obtains the set of source format encodings from which format conversion services are provided by this provider.

  Returns:

  array of source format encodings. If for some reason provider does not provide any conversion services, an array of length 0 is returned.

• getTargetEncodings

  public abstract AudioFormat.Encoding[] getTargetEncodings()

  Obtains the set of target format encodings to which format conversion services are provided by this provider.

  Returns:

  array of target format encodings. If for some reason provider does not provide any conversion services, an array of length 0 is returned.

• isSourceEncodingSupported

  public boolean isSourceEncodingSupported(AudioFormat.Encoding sourceEncoding)

  Indicates whether the format converter supports conversion from the specified source format encoding.

  Parameters:

  sourceEncoding - the source format encoding for which support is queried

  Returns:

  true if the encoding is supported, otherwise false

• isTargetEncodingSupported

  public boolean isTargetEncodingSupported(AudioFormat.Encoding targetEncoding)

  Indicates whether the format converter supports conversion to the specified target format encoding.

  Parameters:

  targetEncoding - the target format encoding for which support is queried

  Returns:

  true if the encoding is supported, otherwise false

• getTargetEncodings

  public abstract AudioFormat.Encoding[] getTargetEncodings(AudioFormat sourceFormat)

  Obtains the set of target format encodings supported by the format converter given a particular source format. If no target format encodings are supported for this source format, an array of length 0 is returned.

  Parameters:

  sourceFormat - format of the incoming data

  Returns:

  array of supported target format encodings.

• isConversionSupported

  public boolean isConversionSupported(AudioFormat.Encoding targetEncoding,
                                       AudioFormat sourceFormat)

  Indicates whether the format converter supports conversion to a particular encoding from a particular format.

  Parameters:

  targetEncoding - desired encoding of the outgoing data

  sourceFormat - format of the incoming data

  Returns:

  true if the conversion is supported, otherwise false

• getTargetFormats

  public abstract AudioFormat[] getTargetFormats(AudioFormat.Encoding targetEncoding,
                                                 AudioFormat sourceFormat)

  Obtains the set of target formats with the encoding specified supported by the format converter If no target formats with the specified encoding are supported for this source format, an array of length 0 is returned.

  Parameters:

  targetEncoding - desired encoding of the stream after processing

  sourceFormat - format of the incoming data

  Returns:

  array of supported target formats.

• isConversionSupported

  public boolean isConversionSupported(AudioFormat targetFormat,
                                       AudioFormat sourceFormat)

  Indicates whether the format converter supports conversion to one particular format from another.

  Parameters:

  targetFormat - desired format of outgoing data

  sourceFormat - format of the incoming data

  Returns:

  true if the conversion is supported, otherwise false

• getAudioInputStream

  public abstract AudioInputStream getAudioInputStream(AudioFormat.Encoding targetEncoding,
                                                       AudioInputStream sourceStream)

  Obtains an audio input stream with the specified encoding from the given audio input stream.

  Parameters:

  targetEncoding - desired encoding of the stream after processing

  sourceStream - stream from which data to be processed should be read

  Returns:

  stream from which processed data with the specified target encoding may be read

  Throws:

  IllegalArgumentException - if the format combination supplied is not supported.

• getAudioInputStream

  public abstract AudioInputStream getAudioInputStream(AudioFormat targetFormat,
                                                       AudioInputStream sourceStream)

  Obtains an audio input stream with the specified format from the given audio input stream.

  Parameters:

  targetFormat - desired data format of the stream after processing

  sourceStream - stream from which data to be processed should be read

  Returns:

  stream from which processed data with the specified format may be read

  Throws:

  IllegalArgumentException - if the format combination supplied is not supported.
