List of roll() Examples

Examples of roll()

com.ibm.icu.util.Calendar.roll()
Rolls (up/down) a single unit of time on the given field. If the field is rolled past its maximum allowable value, it will "wrap" back to its minimum and continue rolling. For example, to roll the current date up by one day, you can call:
roll( {@link #DATE}, true)
When rolling on the {@link #YEAR} field, it will roll the yearvalue in the range between 1 and the value returned by calling {@link #getMaximum getMaximum}( {@link #YEAR}).
When rolling on certain fields, the values of other fields may conflict and need to be changed. For example, when rolling the MONTH field for the Gregorian date 1/31/96 upward, the DAY_OF_MONTH field must be adjusted so that the result is 2/29/96 rather than the invalid 2/31/96.
Note: Calling roll(field, true) N times is not necessarily equivalent to calling roll(field, N). For example, imagine that you start with the date Gregorian date January 31, 1995. If you call roll(Calendar.MONTH, 2), the result will be March 31, 1995. But if you call roll(Calendar.MONTH, true), the result will be February 28, 1995. Calling it one more time will give March 28, 1995, which is usually not the desired result.
Note: You should always use roll and add rather than attempting to perform arithmetic operations directly on the fields of a Calendar. It is quite possible for Calendar subclasses to have fields with non-linear behavior, for example missing months or days during non-leap years. The subclasses' add and roll methods will take this into account, while simple arithmetic manipulations may give invalid results.
@param field the calendar field to roll. @param up indicates if the value of the specified time field is to berolled up or rolled down. Use true if rolling up, false otherwise. @exception IllegalArgumentException if the field is invalid or refersto a field that cannot be handled by this method. @see #roll(int,int) @see #add @stable ICU 2.0

java.util.Calendar.roll()
Adds or subtracts (up/down) a single unit of time on the given time field without changing larger fields. For example, to roll the current date up by one day, you can achieve it by calling:
roll(Calendar.DATE, true). When rolling on the year or Calendar.YEAR field, it will roll the year value in the range between 1 and the value returned by calling getMaximum(Calendar.YEAR). When rolling on the month or Calendar.MONTH field, other fields like date might conflict and, need to be changed. For instance, rolling the month on the date 01/31/96 will result in 02/29/96. When rolling on the hour-in-day or Calendar.HOUR_OF_DAY field, it will roll the hour value in the range between 0 and 23, which is zero-based. @param field the time field. @param up indicates if the value of the specified time field is to berolled up or rolled down. Use true if rolling up, false otherwise. @see Calendar#add(int,int) @see Calendar#set(int,int)
java.util.GregorianCalendar.roll()
Adds or subtracts (up/down) a single unit of time on the given time field without changing larger fields.
Example: Consider a GregorianCalendar originally set to December 31, 1999. Calling {@link #roll(int,boolean) roll(Calendar.MONTH, true)}sets the calendar to January 31, 1999. The YEAR field is unchanged because it is a larger field than MONTH.
@param up indicates if the value of the specified calendar field is to berolled up or rolled down. Use true if rolling up, false otherwise. @exception IllegalArgumentException if field isZONE_OFFSET, DST_OFFSET, or unknown, or if any calendar fields have out-of-range values in non-lenient mode. @see #add(int,int) @see #set(int,int)
