  /**
   * Specifies the format of a CSV file for parsing and writing.
   *
   * <h2>Using predefined formats</h2>
   *
   * <p>
   * You can use one of the predefined formats:
   * </p>
   *
   * <ul>
   * <li>{@link #DEFAULT}</li>
   * <li>{@link #EXCEL}</li>
   * <li>{@link #INFORMIX_UNLOAD}</li>
   * <li>{@link #INFORMIX_UNLOAD_CSV}</li>
   * <li>{@link #MONGODB_CSV}</li>
   * <li>{@link #MONGODB_TSV}</li>
   * <li>{@link #MYSQL}</li>
   * <li>{@link #ORACLE}</li>
   * <li>{@link #POSTGRESQL_CSV}</li>
   * <li>{@link #POSTGRESQL_TEXT}</li>
   * <li>{@link #RFC4180}</li>
   * <li>{@link #TDF}</li>
   * </ul>
   *
   * <p>
   * For example:
   * </p>
   *
   * <pre>
   * CSVParser parser = CSVFormat.EXCEL.parse(reader);
   * </pre>
   *
   * <p>
   * The {@link CSVParser} provides static methods to parse other input types, for example:
   * </p>
   *
   * <pre>
   * CSVParser parser = CSVParser.parse(file, StandardCharsets.US_ASCII, CSVFormat.EXCEL);
   * </pre>
   *
   * <h2>Defining formats</h2>
   *
   * <p>
   * You can extend a format by calling the {@code set} methods. For example:
   * </p>
   *
   * <pre>{@code
   * CSVFormat.EXCEL.builder().setNullString("N/A").setIgnoreSurroundingSpaces(true).get();
   * }</pre>
   *
  * <h2>Defining column names</h2>
  *
  * <p>
  * To define the column names you want to use to access records, write:
  * </p>
  *
  * <pre>{@code
  * CSVFormat.EXCEL.builder().setHeader("Col1", "Col2", "Col3").get();
  * }</pre>
  *
  * <p>
  * Calling {@link Builder#setHeader(String...)} lets you use the given names to address values in a {@link CSVRecord}, and assumes that your CSV source does not
  * contain a first record that also defines column names.
  *
  * If it does, then you are overriding this metadata with your names and you should skip the first record by calling
  * {@link Builder#setSkipHeaderRecord(boolean)} with {@code true}.
  * </p>
  *
  * <h2>Parsing</h2>
  *
  * <p>
  * You can use a format directly to parse a reader. For example, to parse an Excel file with columns header, write:
  * </p>
  *
  * <pre>{@code
  * Reader in = ...;
  * CSVFormat.EXCEL.builder().setHeader("Col1", "Col2", "Col3").get().parse(in);
  * }</pre>
  *
  * <p>
  * For other input types, like resources, files, and URLs, use the static methods on {@link CSVParser}.
  * </p>
  *
  * <h2>Referencing columns safely</h2>
  *
  * <p>
  * If your source contains a header record, you can simplify your code and safely reference columns, by using {@link Builder#setHeader(String...)} with no
  * arguments:
  * </p>
  *
  * <pre>
  * CSVFormat.EXCEL.builder().setHeader().get();
  * </pre>
  *
  * <p>
  * This causes the parser to read the first record and use its values as column names.
  *
  * Then, call one of the {@link CSVRecord} get method that takes a String column name argument:
  * </p>
  *
  * <pre>{@code
  * String value = record.get("Col1");
  * }</pre>
  *
  * <p>
  * This makes your code impervious to changes in column order in the CSV file.
  * </p>
  *
  * <h2>Serialization</h2>
  * <p>
  * This class implements the {@link Serializable} interface with the following caveats:
  * </p>
  * <ul>
  * <li>This class will no longer implement Serializable in 2.0.</li>
  * <li>Serialization is not supported from one version to the next.</li>
  * </ul>
  * <p>
  * The {@code serialVersionUID} values are:
  * </p>
  * <ul>
  * <li>Version 1.10.0: {@code 2L}</li>
  * <li>Version 1.9.0 through 1.0: {@code 1L}</li>
  * </ul>
  *
  * <h2>Notes</h2>
  * <p>
  * This class is immutable.
  * </p>
  * <p>
  * Not all settings are used for both parsing and writing.
  * </p>
