Class SimpleDate

java.lang.Object
  rsvp.model.SimpleDate

All Implemented Interfaces:

java.io.Serializable

public class SimpleDate
extends java.lang.Object
implements java.io.Serializable

SimpleDate is a very simple representation of a calendar date and time. Notably, it only represents dates in the Gregorian calendar system (with American English month names) and does not account for separate time zones. However, it does validate that the date and time it stores are actually possible, given the Gregorian calendar and a 24-hour clock. (It will, however, be inaccurate for dates from before the introduction of the Gregorian calendar.)

Method Detail

isValid

public boolean isValid()

Returns true if this SimpleDate is valid -- that is, does this SimpleDate correspond to a legitimate date in the Gregorian calendar? -- and false otherwise. A SimpleDate is valid if the hour is between 0 and 23, the minute is between 0 and 59, the month is between 1 and 12, and the day is between 1 and the number of days in the given month and year, inclusive. (Note that 12:00 on 2/29/2007 is invalid, while 12:00 on 2/29/2000 would be.)
