/** |
|
32 |
* The class <code>Era</code> represents a calendar era that defines a |
|
33 |
* period of time in which the same year numbering is used. For |
|
34 |
* example, Gregorian year 2004 is <I>Heisei</I> 16 in the Japanese |
|
35 |
* calendar system. An era starts at any point of time (Gregorian) that is |
|
36 |
* represented by <code>CalendarDate</code>. |
|
37 |
* |
|
38 |
* <p><code>Era</code>s that are applicable to a particular calendar |
|
39 |
* system can be obtained by calling {@link CalendarSystem#getEras} |
|
40 |
* one of which can be used to specify a date in |
|
41 |
* <code>CalendarDate</code>. |
|
42 |
* |
|
43 |
* <p>The following era names are defined in this release. |
