| 20 * \brief C API: DateFormat | |
| 21 * | |
| 22 * <h2> Date Format C API</h2> | |
| 23 * | |
| 24 * Date Format C API consists of functions that convert dates and | |
| 25 * times from their internal representations to textual form and back again in a | |
| 26 * language-independent manner. Converting from the internal representation (mil
liseconds | |
| 27 * since midnight, January 1, 1970) to text is known as "formatting," and conver
ting | |
| 28 * from text to millis is known as "parsing." We currently define only one conc
rete | |
| 29 * structure UDateFormat, which can handle pretty much all normal | |
| 30 * date formatting and parsing actions. | |
| 31 * <P> | |
| 32 * Date Format helps you to format and parse dates for any locale. Your code can | |
| 33 * be completely independent of the locale conventions for months, days of the | |
| 34 * week, or even the calendar format: lunar vs. solar. | |
| 35 * <P> | |
| 36 * To format a date for the current Locale with default time and date style, | |
| 37 * use one of the static factory methods: | |
| 38 * <pre> | |
| 39 * \code | |
| 40 * UErrorCode status = U_ZERO_ERROR; | |
| 41 * UChar *myString; | |
| 42 * int32_t myStrlen = 0; | |
| 43 * UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NU
LL, -1, &status); | |
| 44 * myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, NULL, &status); | |
| 45 * if (status==U_BUFFER_OVERFLOW_ERROR){ | |
| 46 * status=U_ZERO_ERROR; | |
| 47 * myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) ); | |
| 48 * udat_format(dfmt, myDate, myString, myStrlen+1, NULL, &status); | |
| 49 * } | |
| 50 * \endcode | |
| 51 * </pre> | |
| 52 * If you are formatting multiple numbers, it is more efficient to get the | |
| 53 * format and use it multiple times so that the system doesn't have to fetch the | |
| 54 * information about the local language and country conventions multiple times. | |
| 55 * <pre> | |
| 56 * \code | |
| 57 * UErrorCode status = U_ZERO_ERROR; | |
| 58 * int32_t i, myStrlen = 0; | |
| 59 * UChar* myString; | |
| 60 * char buffer[1024]; | |
| 61 * UDate myDateArr[] = { 0.0, 100000000.0, 2000000000.0 }; // test values | |
| 62 * UDateFormat* df = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NULL
, 0, &status); | |
| 63 * for (i = 0; i < 3; i++) { | |
| 64 * myStrlen = udat_format(df, myDateArr[i], NULL, myStrlen, NULL, &status); | |
| 65 * if(status == U_BUFFER_OVERFLOW_ERROR){ | |
| 66 * status = U_ZERO_ERROR; | |
| 67 * myString = (UChar*)malloc(sizeof(UChar) * (myStrlen+1) ); | |
| 68 * udat_format(df, myDateArr[i], myString, myStrlen+1, NULL, &status); | |
| 69 * printf("%s\n", u_austrcpy(buffer, myString) ); | |
| 70 * free(myString); | |
| 71 * } | |
| 72 * } | |
| 73 * \endcode | |
| 74 * </pre> | |
| 75 * To get specific fields of a date, you can use UFieldPosition to | |
| 76 * get specific fields. | |
| 77 * <pre> | |
| 78 * \code | |
| 79 * UErrorCode status = U_ZERO_ERROR; | |
| 80 * UFieldPosition pos; | |
| 81 * UChar *myString; | |
| 82 * int32_t myStrlen = 0; | |
| 83 * char buffer[1024]; | |
| 84 * | |
| 85 * pos.field = 1; // Same as the DateFormat::EField enum | |
| 86 * UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, -1, NULL, 0,
&status); | |
| 87 * myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, &pos, &status); | |
| 88 * if (status==U_BUFFER_OVERFLOW_ERROR){ | |
| 89 * status=U_ZERO_ERROR; | |
| 90 * myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) ); | |
| 91 * udat_format(dfmt, myDate, myString, myStrlen+1, &pos, &status); | |
| 92 * } | |
| 93 * printf("date format: %s\n", u_austrcpy(buffer, myString)); | |
| 94 * buffer[pos.endIndex] = 0; // NULL terminate the string. | |
| 95 * printf("UFieldPosition position equals %s\n", &buffer[pos.beginIndex]); | |
| 96 * \endcode | |
| 97 * </pre> | |
| 98 * To format a date for a different Locale, specify it in the call to | |
| 99 * udat_open() | |
| 100 * <pre> | |
| 101 * \code | |
| 102 * UDateFormat* df = udat_open(UDAT_SHORT, UDAT_SHORT, "fr_FR", NULL, -1,
NULL, 0, &status); | |
| 103 * \endcode | |
| 104 * </pre> | |
| 105 * You can use a DateFormat API udat_parse() to parse. | |
| 106 * <pre> | |
| 107 * \code | |
| 108 * UErrorCode status = U_ZERO_ERROR; | |
| 109 * int32_t parsepos=0; | |
| 110 * UDate myDate = udat_parse(df, myString, u_strlen(myString), &parsepos, &stat
us); | |
| 111 * \endcode | |
| 112 * </pre> | |
| 113 * You can pass in different options for the arguments for date and time style | |
| 114 * to control the length of the result; from SHORT to MEDIUM to LONG to FULL. | |
| 115 * The exact result depends on the locale, but generally: | |
| 116 * see UDateFormatStyle for more details | |
| 117 * <ul type=round> | |
| 118 * <li> UDAT_SHORT is completely numeric, such as 12/13/52 or 3:30pm | |
| 119 * <li> UDAT_MEDIUM is longer, such as Jan 12, 1952 | |
| 120 * <li> UDAT_LONG is longer, such as January 12, 1952 or 3:30:32pm | |
| 121 * <li> UDAT_FULL is pretty completely specified, such as | |
| 122 * Tuesday, April 12, 1952 AD or 3:30:42pm PST. | |
| 123 * </ul> | |
| 124 * You can also set the time zone on the format if you wish. | |
| 125 * <P> | |
| 126 * You can also use forms of the parse and format methods with Parse Position an
d | |
| 127 * UFieldPosition to allow you to | |
| 128 * <ul type=round> | |
| 129 * <li> Progressively parse through pieces of a string. | |
| 130 * <li> Align any particular field, or find out where it is for selection | |
| 131 * on the screen. | |
| 132 * </ul> | |
