First embodiment provided by the invention comprises two parts:
Step 1 is based on the time on timing date of plan scheduler task in the Crontab character string definition timing iterator.
In this step, at first based on the Crontab character string, the Boolean type array is set in the timing iterator representes the time on date respectively, then, the value in the Boolean type array of the time on date of planned dispatching task correspondence is set to actual value.
Specify the concrete implementation procedure of this step below for example:
As, with 5 Boolean type arrays come to represent respectively minute, hour, day, month, week, array length is respectively 60,24,31,12 and 7, is worth for true representes the array moment corresponding to satisfy definition.
Suppose to realize 5 a certain timed tasks of execution in every month 1 to 15 morning every three days, then the crontab character string is:
0?5?1-15/2**
Corresponding array is respectively:
Minute the 0th value of array is true, and other are false;
Hour the 5th value of array is true, and other are false;
The 0th, 2,4,6,8,10,12,14 values of day array are true, and other are false;
The all values of moon array are true;
The all values of week array are true.
Step 2, next time execution date that the planned dispatching task is obtained in realization according to the timing iterator after the definition.
In this step, at first need calculate the time on date and the difference of base period between the time of planned dispatching task, need the initial value of a base period time before calculating, this value can ownly define, and also can give tacit consent to from the current date time to begin.Then, the present invention obtains time execution date next time of satisfying definition in the planned dispatching task according to said calculated difference, and according to the task of being obtained of the date time scheduling planning execution of execution next time.Concrete implementation procedure,, as shown in Figure 1 with acquiescence from the current date time, comprising:
Step S101 calculates the timing month of said planned dispatching task and the difference between current month.
Step S102 judges that whether said difference is greater than 0.
If said difference is greater than 0; Then represent to satisfy definition by certain moon after current month; So execution in step S103 promptly adjusts the current date time and is: keep the time constant, current month is added the above difference; With the day in the said time on date, date in week, hour and minute be set to 1 day, 1 week, and 0 minute, execution in step S101 then at 0 o'clock.
If said difference is not more than 0, then execution in step S104 judges that promptly whether said difference is less than 0; If said difference, is then represented certain month of next year less than 0 and is satisfied definition, so execution in step S105; Promptly adjusting the current date time is: current month is added the above difference; The time of current date in the time added 1, with the day in the said time on date, date in week, hour and minute be set to 1 day, 1 week, and 0 minute, execution in step S101 then at 0 o'clock; Otherwise, represent current month to satisfy definition then direct execution in step S111.
Step S111 calculates the timing day and current in the daytime the difference of said planned dispatching task.
Step S112 judges that whether said difference is greater than 0.
If said difference is greater than 0; Then represent satisfied definition one day after current day; So execution in step S113; Promptly adjusting the current date time is: ought add said difference the day before yesterday, keep time and month constant, with all dates in the said time on date, hour and minute be set to 1 week, and 0 minute at 0 o'clock; Execution in step S101 then.
If said difference is not more than 0, then execution in step S114 judges that promptly whether said difference is less than 0; If said difference, is then represented current one day a few days ago less than 0 and is satisfied definition, that is to say; Satisfy definition the one day of next month; So execution in step S115 promptly adjusts current date and is: ought add said difference the day before yesterday, and the month in the current date is added 1; And adjust month and time in the said time on date according to the calendar algorithm, and with all dates in the said time on date, hour and minute be set to 1 week, and 0 minute at 0 o'clock; Execution in step S101 then; Otherwise definition was satisfied in expression when the day before yesterday, then direct execution in step S121.
Step S121 calculates all dates and the difference during current Sunday in time on date of said planned dispatching task.
Step S122 judges that whether said difference is greater than 0.
If said difference is greater than 0; Then represent certain expiration on Sunday foot definition of after date on current Sunday; So execution in step S123; Promptly adjusting the current date time is: current week is added said difference on the date, and according to calendar algorithm adjustment time, month and day, with in the said time on date hour and minute be set to 0 o'clock and 0 minute; Execution in step S101 then.
If said difference is not more than 0, then execution in step S124 judges that promptly whether said difference is less than 0; If said difference is less than 0; Then represent next week on date in current week to satisfy definition, so execution in step S125 promptly adjusts the current date time and is: the current date in week is added said difference; And obtain next week that adds all dates after the above difference according to the calendar algorithm; And according to calendar algorithm adjustment time, month and day, with in the said time on date hour and minute be set to 0 o'clock and 0 minute, execution in step S101 then; Otherwise represent the definition of current expiration on Sunday foot, then direct execution in step S131.
Step S131 calculates timing hour and the difference between current hour in time on date of said planned dispatching task.
Step S132 judges that whether said difference is greater than 0.
If said difference is greater than 0; Then represent the satisfied definition in certain hour after current hour; So execution in step S133 promptly adjusts the current date time and is: keep time, month and day constant, with adding the above difference in current hour; And keep time, month and day constant, with minute being set to 0 fen in the said time on date; Execution in step S101 then.
If said difference is not more than 0, then execution in step S134 judges that promptly whether said difference is less than 0; If said difference, is then represented certain hour after current day less than 0 and is satisfied definition, so execution in step S135; Promptly adjusting the current date time is: with adding the above difference in current hour; And ought add 1 the day before yesterday, and according to calendar algorithm adjustment time, month and day, with minute being set to 0 fen in the said time on date; Execution in step S101 then; Otherwise represent satisfied definition in current hour, then direct execution in step S141.
Step S141, calculate in time on date of said planned dispatching task minute and current date in the time minute between difference.
Step S142 judges that whether said difference is greater than 0.
If said difference greater than 0, is then represented after current minute certain minute to satisfy definition, so execution in step S143 promptly adjusts the current date time and is: keep time, month, day and hour constant, current date minute is added the above difference in the time; Execution in step S141 then.
If said difference is not more than 0, then execution in step S144 judges that promptly whether said difference is less than 0; If said difference is less than 0; Then represent after current hour certain minute to satisfy definition, so execution in step S135 promptly adjusts the current date time and is: current date minute is added the above difference in the time; And current date hour added 1 in the time, and according to calendar algorithm adjustment time, month and day; Execution in step S141 then; Otherwise represent satisfied definition in current minute, then direct execution in step S141.
Step S141 confirms that the current date time of obtaining is the time on date of planned dispatching.
The second embodiment of the present invention, the places different with first embodiment be, do not comprise the process of between step 121 to step 125, when judge when the day before yesterday satisfy define after, directly turn to step S131.
Specify the implementation process of second embodiment below for example:
Suppose that planned time is every month 1: 10 on the 5th, the current time is a point 6 days 13 May in 2005.The process of obtaining the concrete time of next time carrying out so is:
Step 1 compares month, because planned time is every month, so meet the demands execution in step two certainly.
Step 2, relatively date: plan day is 5, is 6 when the day before yesterday, and the difference of the two is-1; So current month is added 1, and current date becomes: 6+ (1)=5, hour be adjusted into 0, minute be adjusted into 0; At this moment the current time becomes 0: 0 on the 5th June in 2005, and execution in step one then, and relatively month, the month of planned time this moment is every month; So satisfy definition, its difference with current month is 0, so the step 2 of turning to continues the comparison date; Plan day this moment is 5, also is 5 when the day before yesterday, and the difference of the two all is 0, and execution in step three then;
Step 3, when smaller: plan hour is 1 point, and current hour is 0 point, and the difference of the two is 1, then adjusts current date: current hourage is directly added 1, and execution in step one then, the difference of this moment month, day, hour is 0, turns to step 4;
Step 4, relatively minute, difference is 10, minute adds 10, the time of this moment is 1: 10 on the 5th June in 2005.Confirm that promptly the current date time of obtaining is the time on date of planned dispatching.Execution time.
