|
|
|
* This class is an abstract base class for Calendars, which can be
|
|
|
|
* used to convert between <code>Date</code> objects and a set of
|
|
|
|
* integer fields which represent <code>YEAR</code>,
|
|
|
|
* <code>MONTH</code>, <code>DAY</code>, etc. The <code>Date</code>
|
|
|
|
* object represents a time in milliseconds since the Epoch. <br>
|
|
|
|
*
|
|
|
|
* This class is locale sensitive. To get the Object matching the
|
|
|
|
* current locale you can use <code>getInstance</code>. You can even provide
|
|
|
|
* a locale or a timezone. <code>getInstance</code> returns currently
|
|
|
|
* a <code>GregorianCalendar</code> for the current date. <br>
|
|
|
|
*
|
|
|
|
* If you want to convert a date from the Year, Month, Day, DayOfWeek,
|
|
|
|
* etc. Representation to a <code>Date</code>-Object, you can create
|
|
|
|
* a new Calendar with <code>getInstance()</code>,
|
|
|
|
* <code>clear()</code> all fields, <code>set(int,int)</code> the
|
|
|
|
* fields you need and convert it with <code>getTime()</code>. <br>
|
|
|
|
*
|
|
|
|
* If you want to convert a <code>Date</code>-object to the Calendar
|
|
|
|
* representation, create a new Calendar, assign the
|
|
|
|
* <code>Date</code>-Object with <code>setTime()</code>, and read the
|
|
|
|
* fields with <code>get(int)</code>. <br>
|
|
|
|
*
|
|
|
|
* When computing the date from time fields, it may happen, that there
|
|
|
|
* are either two few fields set, or some fields are inconsistent. This
|
2001-05-10 20:13:17 +02:00
|
|
|
* cases will handled in a calendar specific way. Missing fields are
|
2000-10-27 12:33:46 +02:00
|
|
|
* replaced by the fields of the epoch: 1970 January 1 00:00. <br>
|
|
|
|
*
|
|
|
|
* To understand, how the day of year is computed out of the fields
|
|
|
|
* look at the following table. It is traversed from top to bottom,
|
|
|
|
* and for the first line all fields are set, that line is used to
|
|
|
|
* compute the day. <br>

|
|
|

|
|
|
|
*
|
|
|
|
* Other useful things you can do with an calendar, is
|
|
|
|
* <code>roll</code>ing fields (that means increase/decrease a
|
|
|
|
* specific field by one, propagating overflows), or
|
|
|
|
* <code>add</code>ing/substracting a fixed amount to a field.
