◆ CronEntryUtilities()

eu.baltrad.beast.scheduler.CronEntryUtilities.CronEntryUtilities ( )

inline

Constructor.

Member Function Documentation

◆ createBasePattern()

String eu.baltrad.beast.scheduler.CronEntryUtilities.createBasePattern ( List< String > values )

inline

Creates a base expression from a list of values or intervals.

I.e. it is allowed to specify a sequence like 3,5,*/2 which would mean every second value and also value 3 and 5. Only allowed characters are 0-9 - * and /. I.e. separator character , is not allowed since it will be used to concatenate the strings.

Parameters

values a list of values

Returns: the string pattern

◆ createDayOfMonthPattern()

String eu.baltrad.beast.scheduler.CronEntryUtilities.createDayOfMonthPattern ( List< String > values )

inline

Creates a day of month pattern.

Parameters

values the day of month patterns

Returns: the day of month pattern

◆ createDayOfWeekPattern()

String eu.baltrad.beast.scheduler.CronEntryUtilities.createDayOfWeekPattern ( List< String > values )

inline

Creates a day of week pattern.

Parameters

values the day of week patterns

Returns: the day of week pattern

		List< String >	daysOfWeek )

inline

Creates a cron expression from provided entries.

Parameters

seconds	the second patterns
minutes	the minute patterns
hours	the hour patterns
daysOfMonth	the day of month patterns
