[0065] The first embodiment provided by the present invention includes two parts:

[0066] Step 1. Define the timing date and time of the scheduled task in the timing iterator based on the Crontab string.

[0067] In this step, based on the Crontab string, set the Boolean array in the timing iterator to represent the date and time respectively, and then set the value in the Boolean array corresponding to the date and time of the scheduled task as the real value.

[0068] The following example describes the specific implementation process of this step in detail:

[0069] For example, five Boolean arrays are used to represent minutes, hours, days, months, and weeks respectively, and the lengths of the arrays are 60, 24, 31, 12, and 7 respectively. The value of true indicates that the time corresponding to the array meets the definition.

[0070] Assuming that a certain scheduled task is to be executed at 5 am every two days from the 1st to the 15th of each month, the crontab st...

Abstract

The present invention relates to a method for obtaining execution time of timed task. Its kernel lies in that firstly, based on Crontab character string the planning date time of plan-scheduled task in timing iterator can be defined, then based on described timing iterator the next execution date time of plan-scheduled task can be obtained, so that said invention can utilize one timing iterator to obtain any complex timed task execution time.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for acquiring the execution time of a scheduled task. Background technique [0002] With the development of information technology, the requirements for planning and scheduling are becoming more and more extensive. For example, enterprises need to plan and schedule daily logs or evening batch processing; users need to schedule alarm times according to agreed plans, and so on. Therefore, there is an urgent need to develop applications that can implement planning and scheduling. [0003] crontab is a command of the Unix system. By defining simple character strings, it can complete complex plan definitions and provide the function of date scheduling. [0004] When using the crontab command to define a character string (hereinafter referred to as the crontab character string), the character string is separated into 5 parts by spaces: f1 f2 f3 f4 f5. Among them, f1 represe...
