/** |
|
64 |
* The <code>Calendar</code> class is an abstract class that provides methods |
|
65 |
* for converting between a specific instant in time and a set of {@link |
|
66 |
* #fields calendar fields} such as <code>YEAR</code>, <code>MONTH</code>, |
|
67 |
* <code>DAY_OF_MONTH</code>, <code>HOUR</code>, and so on, and for |
|
68 |
* manipulating the calendar fields, such as getting the date of the next |
|
69 |
* week. An instant in time can be represented by a millisecond value that is |
|
70 |
* an offset from the <a name="Epoch"><em>Epoch</em></a>, January 1, 1970 |
|
71 |
* 00:00:00.000 GMT (Gregorian). |
|
72 |
* |
|
73 |
* <p>The class also provides additional fields and methods for |
|
74 |
* implementing a concrete calendar system outside the package. Those |
|
75 |
* fields and methods are defined as <code>protected</code>. |
|
76 |
* |
|
77 |
* <p> |
|
78 |
* Like other locale-sensitive classes, <code>Calendar</code> provides a |
|
79 |
* class method, <code>getInstance</code>, for getting a generally useful |
|
80 |
* object of this type. <code>Calendar</code>'s <code>getInstance</code> method |
|
81 |
* returns a <code>Calendar</code> object whose |
|
82 |
* calendar fields have been initialized with the current date and time: |
|
83 |
* <blockquote> |
|
84 |
* <pre> |
|
85 |
* Calendar rightNow = Calendar.getInstance(); |
|
86 |
* </pre> |
|
87 |
* </blockquote> |
|
88 |
* |
|
89 |
* <p>A <code>Calendar</code> object can produce all the calendar field values |
|
90 |
* needed to implement the date-time formatting for a particular language and |
|
91 |
* calendar style (for example, Japanese-Gregorian, Japanese-Traditional). |
|
92 |
* <code>Calendar</code> defines the range of values returned by |
|
93 |
* certain calendar fields, as well as their meaning. For example, |
|
94 |
* the first month of the calendar system has value <code>MONTH == |
|
95 |
* JANUARY</code> for all calendars. Other values are defined by the |
|
96 |
* concrete subclass, such as <code>ERA</code>. See individual field |
|
97 |
* documentation and subclass documentation for details. |
|
98 |
* |
|
99 |
* <h4>Getting and Setting Calendar Field Values</h4> |
|
100 |
* |
|
101 |
* <p>The calendar field values can be set by calling the <code>set</code> |
|
102 |
* methods. Any field values set in a <code>Calendar</code> will not be |
|
103 |
* interpreted until it needs to calculate its time value (milliseconds from |
|
104 |
* the Epoch) or values of the calendar fields. Calling the |
|
105 |
* <code>get</code>, <code>getTimeInMillis</code>, <code>getTime</code>, |
|
106 |
* <code>add</code> and <code>roll</code> involves such calculation. |
|
107 |
* |
|
108 |
* <h4>Leniency</h4> |
|
109 |
* |
|
110 |
* <p><code>Calendar</code> has two modes for interpreting the calendar |
|
111 |
* fields, <em>lenient</em> and <em>non-lenient</em>. When a |
|
112 |
* <code>Calendar</code> is in lenient mode, it accepts a wider range of |
|
113 |
* calendar field values than it produces. When a <code>Calendar</code> |
|
114 |
* recomputes calendar field values for return by <code>get()</code>, all of |
|
115 |
* the calendar fields are normalized. For example, a lenient |
|
116 |
* <code>GregorianCalendar</code> interprets <code>MONTH == JANUARY</code>, |
|
117 |
* <code>DAY_OF_MONTH == 32</code> as February 1. |
|
118 |
||
119 |
* <p>When a <code>Calendar</code> is in non-lenient mode, it throws an |
|
120 |
* exception if there is any inconsistency in its calendar fields. For |
|
121 |
* example, a <code>GregorianCalendar</code> always produces |
|
122 |
* <code>DAY_OF_MONTH</code> values between 1 and the length of the month. A |
|
123 |
* non-lenient <code>GregorianCalendar</code> throws an exception upon |
|
124 |
* calculating its time or calendar field values if any out-of-range field |
|
125 |
* value has been set. |
|

* <h4><a name="first_week">First Week</a></h4> |
2 | 128 |
* |
129 |
* <code>Calendar</code> defines a locale-specific seven day week using two |
|
130 |
* parameters: the first day of the week and the minimal days in first week |
|
131 |
* (from 1 to 7). These numbers are taken from the locale resource data when a |
|
132 |
* <code>Calendar</code> is constructed. They may also be specified explicitly |
|
133 |
* through the methods for setting their values. |
|
134 |
* |
|
135 |
* <p>When setting or getting the <code>WEEK_OF_MONTH</code> or |
|
136 |
* <code>WEEK_OF_YEAR</code> fields, <code>Calendar</code> must determine the |
|
137 |
* first week of the month or year as a reference point. The first week of a |
|
138 |
* month or year is defined as the earliest seven day period beginning on |
|
139 |
* <code>getFirstDayOfWeek()</code> and containing at least |
|
140 |
* <code>getMinimalDaysInFirstWeek()</code> days of that month or year. Weeks |
|
141 |
* numbered ..., -1, 0 precede the first week; weeks numbered 2, 3,... follow |
|
142 |
* it. Note that the normalized numbering returned by <code>get()</code> may be |
|
143 |
* different. For example, a specific <code>Calendar</code> subclass may |
|
144 |
* designate the week before week 1 of a year as week <code><i>n</i></code> of |
|
145 |
* the previous year. |
|
146 |
* |
|
147 |
* <h4>Calendar Fields Resolution</h4> |
|
148 |
* |
|
149 |
* When computing a date and time from the calendar fields, there |
|
150 |
* may be insufficient information for the computation (such as only |
|
151 |
* year and month with no day of month), or there may be inconsistent |
|
152 |
* information (such as Tuesday, July 15, 1996 (Gregorian) -- July 15, |
|
153 |
* 1996 is actually a Monday). <code>Calendar</code> will resolve |
|
154 |
* calendar field values to determine the date and time in the |
|
155 |
* following way. |

* <p>If there are any calendar fields whose values haven't been set in the selected |

|
182 |
* value of each field may vary by concrete calendar systems. For example, in |
|
183 |
* <code>GregorianCalendar</code>, the default of a field is the same as that |
|
184 |
* of the start of the Epoch: i.e., <code>YEAR = 1970</code>, <code>MONTH = |
|
185 |
* JANUARY</code>, <code>DAY_OF_MONTH = 1</code>, etc. |
|
186 |
* |
|
187 |
* <p> |
|
188 |
* <strong>Note:</strong> There are certain possible ambiguities in |
|
189 |
* interpretation of certain singular times, which are resolved in the |
|
190 |
* following ways: |
|
191 |
* <ol> |
|
192 |
* <li> 23:59 is the last minute of the day and 00:00 is the first |
|
193 |
* minute of the next day. Thus, 23:59 on Dec 31, 1999 < 00:00 on |
|
194 |
* Jan 1, 2000 < 00:01 on Jan 1, 2000. |
|
195 |
* |
|
196 |
* <li> Although historically not precise, midnight also belongs to "am", |
|
197 |
* and noon belongs to "pm", so on the same day, |
|
198 |
* 12:00 am (midnight) < 12:01 am, and 12:00 pm (noon) < 12:01 pm |
|
199 |
* </ol> |
|
200 |
* |
|
201 |
* <p> |
|
202 |
* The date or time format strings are not part of the definition of a |
|
203 |
* calendar, as those must be modifiable or overridable by the user at |
|
204 |
* runtime. Use {@link DateFormat} |
|
205 |
* to format dates. |
|
206 |
* |
|
207 |
* <h4>Field Manipulation</h4> |
|
208 |
* |
|
209 |
* The calendar fields can be changed using three methods: |
|
210 |
* <code>set()</code>, <code>add()</code>, and <code>roll()</code>.</p> |
|
211 |
* |
|
212 |
* <p><strong><code>set(f, value)</code></strong> changes calendar field |
|
213 |
* <code>f</code> to <code>value</code>. In addition, it sets an |
|
214 |
* internal member variable to indicate that calendar field <code>f</code> has |
|
215 |
* been changed. Although calendar field <code>f</code> is changed immediately, |
|
216 |
* the calendar's time value in milliseconds is not recomputed until the next call to |
|
217 |
* <code>get()</code>, <code>getTime()</code>, <code>getTimeInMillis()</code>, |
|
218 |
* <code>add()</code>, or <code>roll()</code> is made. Thus, multiple calls to |
|
219 |
* <code>set()</code> do not trigger multiple, unnecessary |
|
220 |
* computations. As a result of changing a calendar field using |
|
221 |
* <code>set()</code>, other calendar fields may also change, depending on the |
|
222 |
* calendar field, the calendar field value, and the calendar system. In addition, |
|
223 |
* <code>get(f)</code> will not necessarily return <code>value</code> set by |
|
224 |
* the call to the <code>set</code> method |
|
225 |
* after the calendar fields have been recomputed. The specifics are determined by |
|
226 |
* the concrete calendar class.</p> |
|
227 |
* |
|
228 |
* <p><em>Example</em>: Consider a <code>GregorianCalendar</code> |
|
229 |
* originally set to August 31, 1999. Calling <code>set(Calendar.MONTH, |
|
230 |
* Calendar.SEPTEMBER)</code> sets the date to September 31, |
|
231 |
* 1999. This is a temporary internal representation that resolves to |
|
232 |
* October 1, 1999 if <code>getTime()</code>is then called. However, a |
|
233 |
* call to <code>set(Calendar.DAY_OF_MONTH, 30)</code> before the call to |
|
234 |
* <code>getTime()</code> sets the date to September 30, 1999, since |
|
235 |
* no recomputation occurs after <code>set()</code> itself.</p> |
|
236 |
* |
|
237 |
* <p><strong><code>add(f, delta)</code></strong> adds <code>delta</code> |
|
238 |
* to field <code>f</code>. This is equivalent to calling <code>set(f, |
|
239 |
* get(f) + delta)</code> with two adjustments:</p> |
|
240 |
* |
|
241 |
* <blockquote> |
|
242 |
* <p><strong>Add rule 1</strong>. The value of field <code>f</code> |
|
243 |
* after the call minus the value of field <code>f</code> before the |
|
244 |
* call is <code>delta</code>, modulo any overflow that has occurred in |
|
245 |
* field <code>f</code>. Overflow occurs when a field value exceeds its |
|
246 |
* range and, as a result, the next larger field is incremented or |
|
247 |
* decremented and the field value is adjusted back into its range.</p> |
|
248 |
* |
|
249 |
* <p><strong>Add rule 2</strong>. If a smaller field is expected to be |
|
250 |
* invariant, but it is impossible for it to be equal to its |
|
251 |
* prior value because of changes in its minimum or maximum after field |
|
252 |
* <code>f</code> is changed or other constraints, such as time zone |
|
253 |
* offset changes, then its value is adjusted to be as close |
|
254 |
* as possible to its expected value. A smaller field represents a |
|
255 |
* smaller unit of time. <code>HOUR</code> is a smaller field than |
|
256 |
* <code>DAY_OF_MONTH</code>. No adjustment is made to smaller fields |
|
257 |
* that are not expected to be invariant. The calendar system |
|
258 |
* determines what fields are expected to be invariant.</p> |
|
259 |
* </blockquote> |
|
260 |
* |
|
261 |
* <p>In addition, unlike <code>set()</code>, <code>add()</code> forces |
|
262 |
* an immediate recomputation of the calendar's milliseconds and all |
|
263 |
* fields.</p> |
|
264 |
* |
|
265 |
* <p><em>Example</em>: Consider a <code>GregorianCalendar</code> |
|
266 |
* originally set to August 31, 1999. Calling <code>add(Calendar.MONTH, |
|
267 |
* 13)</code> sets the calendar to September 30, 2000. <strong>Add rule |
|
268 |
* 1</strong> sets the <code>MONTH</code> field to September, since |
|
269 |
* adding 13 months to August gives September of the next year. Since |
|
270 |
* <code>DAY_OF_MONTH</code> cannot be 31 in September in a |
|
271 |
* <code>GregorianCalendar</code>, <strong>add rule 2</strong> sets the |
|
272 |
* <code>DAY_OF_MONTH</code> to 30, the closest possible value. Although |
|
273 |
* it is a smaller field, <code>DAY_OF_WEEK</code> is not adjusted by |
|
274 |
* rule 2, since it is expected to change when the month changes in a |
|
275 |
* <code>GregorianCalendar</code>.</p> |
|
276 |
* |
|
277 |
* <p><strong><code>roll(f, delta)</code></strong> adds |
|
278 |
* <code>delta</code> to field <code>f</code> without changing larger |
|
279 |
* fields. This is equivalent to calling <code>add(f, delta)</code> with |
|
280 |
* the following adjustment:</p> |
|
281 |
* |
|
282 |
* <blockquote> |
|
283 |
* <p><strong>Roll rule</strong>. Larger fields are unchanged after the |
|
284 |
* call. A larger field represents a larger unit of |
|
285 |
* time. <code>DAY_OF_MONTH</code> is a larger field than |
|
286 |
* <code>HOUR</code>.</p> |
|
287 |
* </blockquote> |
|
288 |
* |
|
289 |
* <p><em>Example</em>: See {@link java.util.GregorianCalendar#roll(int, int)}. |
|
290 |
* |
|
291 |
* <p><strong>Usage model</strong>. To motivate the behavior of |
|
292 |
* <code>add()</code> and <code>roll()</code>, consider a user interface |
|
293 |
* component with increment and decrement buttons for the month, day, and |
|
294 |
* year, and an underlying <code>GregorianCalendar</code>. If the |
|
295 |
* interface reads January 31, 1999 and the user presses the month |
|
296 |
* increment button, what should it read? If the underlying |

// Data flow in Calendar |
|
316 |
// --------------------- |
|
317 |
||
318 |
// The current time is represented in two ways by Calendar: as UTC |
|
319 |
// milliseconds from the epoch (1 January 1970 0:00 UTC), and as local |
|
320 |
// fields such as MONTH, HOUR, AM_PM, etc. It is possible to compute the |
|
321 |
// millis from the fields, and vice versa. The data needed to do this |
|
322 |
// conversion is encapsulated by a TimeZone object owned by the Calendar. |
|
323 |
// The data provided by the TimeZone object may also be overridden if the |
|
324 |
// user sets the ZONE_OFFSET and/or DST_OFFSET fields directly. The class |
|
325 |
// keeps track of what information was most recently set by the caller, and |
|
326 |
// uses that to compute any other information as needed. |
|
327 |
||
328 |
// If the user sets the fields using set(), the data flow is as follows. |
|
329 |
// This is implemented by the Calendar subclass's computeTime() method. |
|
330 |
// During this process, certain fields may be ignored. The disambiguation |
|
331 |
// algorithm for resolving which fields to pay attention to is described |
|
332 |
// in the class documentation. |
|
333 |
||
334 |
// local fields (YEAR, MONTH, DATE, HOUR, MINUTE, etc.) |
|
335 |
// | |
|
336 |
// | Using Calendar-specific algorithm |
|

// V |

|
341 |
// V |
|

// UTC millis (in time data member) |
|
343 |
||
344 |
// If the user sets the UTC millis using setTime() or setTimeInMillis(), |
|
345 |
// the data flow is as follows. This is implemented by the Calendar |
|
346 |
// subclass's computeFields() method. |

|

|
359 |
// back out to fields is made when necessary. This is implemented by the |
|
360 |
// complete() method. Resolving a partial set of fields into a UTC millis |
|
361 |
// value allows all remaining fields to be generated from that value. If |
|
362 |
// the Calendar is lenient, the fields are also renormalized to standard |
|
363 |
// ranges when they are regenerated. |
