                       throws ManifoldCFException
        Decode the next base64 character. Reads a single encoded word from the input stream, and writes the decoded word to the output.
        Parameters:
        inputBuffer - is the character input stream.
        outputBuffer - is the binary output stream.
        Returns:
        false if end-of-stream encountered, true otherwise
        Throws:
        ManifoldCFException

      • decodeStream

                         java.io.OutputStream outputBuffer)
                  throws ManifoldCFException
        Decode an entire stream.
        Parameters:
        inputBuffer - is the character input stream.
        outputBuffer - is the binary output stream.
        Throws:
        ManifoldCFException

      • decodeString

        public byte[] decodeString​(java.lang.String inputString)
                    throws ManifoldCFException
        Decode a string into a byte array.
        Parameters:
        inputString - is the string.
        Returns:
        a corresponding byte array.
        Throws:
        ManifoldCFException
