/**
 * Creates a printer that will print values to the given stream following the CSVFormat.
 * <p>/*w  ww  .  j  av  a  2s . co m*/
 * Currently, only a pure encapsulation format or a pure escaping format is supported. Hybrid formats (encapsulation
 * and escaping with a different character) are not supported.
 * </p>
 *
 * @param out
 *            stream to which to print. Must not be null.
 * @param format
 *            the CSV format. Must not be null.
 * @throws IOException
 *             thrown if the optional header cannot be printed.
 * @throws IllegalArgumentException
 *             thrown if the parameters of the format are inconsistent or if either out or format are null.
