@FunctionalInterface public interface ChronoCondition<T> extends Predicate<T>

Represents a temporal condition.

Common examples are queries for Friday the thirteenth or if a date matches a holiday or a weekend. This interface is very similar to the type ChronoQuery<T, Boolean> but allows more clarity and does not throw any exception.

      Due to better readability it is recommended to use following equivalent approach instead of this method::

        import static net.time4j.Weekday.SATURDAY;
        import static net.time4j.Month.JANUARY;
        PlainDate date = PlainDate.of(2014, JANUARY, 25);
        System.out.println(SATURDAY.test(date)); // direct use
        System.out.println(date.matches(SATURDAY)); // recommended callback
      Specified by:
      test in interface Predicate<T>
      context - context as base of testing this condition
      true if given time context matches this condition else false
