This is a dynamic decision table. The syntax is the same as that of a DecisionTable, except that the first cell has to be prefixed by ''ddt:'' or ''dynamic decision:''.

The dynamic decision table provides an alternative to the DecisionTable when the GracefulNames of the column headers are not well suited as method names.

The source code of the fixture !-AddUpChange-! looks like this:{{{
public class AddUpChange {
  private Integer totalCents = 0;
  private static Map COIN_VALUES = new HashMap();
  static {
    COIN_VALUES.put("1c", 1);
    COIN_VALUES.put("5c", 5);
    COIN_VALUES.put("10c", 10);
    COIN_VALUES.put("25c", 25);
    COIN_VALUES.put("50c", 50);
    COIN_VALUES.put("$1", 100);
  }

  public void reset() {
    totalCents = 0;
  }

  public void set(String coin, Integer amount) {
    if (!COIN_VALUES.containsKey(coin)) {
      throw new IllegalArgumentException("Unknown coin type " + coin);
    }
    totalCents += amount * COIN_VALUES.get(coin);
  }

  public String get(String requestedValue) {
    if ("$ total".equals(requestedValue)) {
      return String.format(Locale.US, "%.2f", totalCents / 100.0);
    }
    return String.format("%d", totalCents);
  }
}
}}}

The cells with column headers that do not end with a ''?'' are considered inputs and they result in a method call !style_code(set(''header'', ''value'')). The cells with column headers that end with a ''?'' are considered outputs and they result in a method call !style_code(get(''header'')).

Apart from that the same methods are called as for a DecisionTable (!style_code(table), !style_code(beginTable), !style_code(reset), !style_code(execute), !style_code(endTable)).

As in a DecisionTable, all the !style_code(set) method calls are done before the !style_code(execute) call and all the !style_code(get) method calls are done after the !style_code(execute) call.

You can use SymbolsInTables and ValueComparisons as well as comment column headers prefixed with ''#'' and use additional cells as comments.
