Examples of ch.agent.t2.time.Day

ch.agent.t2.time.TimeIndex

A Day is a {@link Time2} with day resolution.The domain label is daily.

Here are four equivalent ways of constructing daily times:

 TimeIndex day1 = new Day("2005-01-01"); TimeIndex day2 = Day.DOMAIN.time("2005-01-01"); TimeIndex day3 = TimeDomainManager.getFactory() .get("daily").time("2005-01-01"); TimeIndex day4 = TimeDomainManager.getFactory() .get(new TimeDomainDefinition("daily", Resolution.DAY, 0L), true) .time("2005-01-01"); assertSame(day1.getTimeDomain(), day2.getTimeDomain()); assertSame(day1.getTimeDomain(), day3.getTimeDomain()); assertSame(day1.getTimeDomain(), day4.getTimeDomain());
