public EncodeRepresentation(Encoding encoding,
                            Representation wrappedRepresentation)
Constructor.

Parameters:
encoding - Encoder algorithm.
wrappedRepresentation - The wrapped representation.
Method Detail

getSupportedEncodings

public static List<Encoding> getSupportedEncodings()
Returns the list of supported encodings.

Returns:
