Class DaysToWorkingDaysConverter

java.lang.Object

pro.taskana.impl.DaysToWorkingDaysConverter

public final class DaysToWorkingDaysConverter
extends Object

The DaysToWorkingDaysConverter provides a method to convert an age in days into an age in working days. Before the method convertDaysToWorkingDays() can be used, the DaysToWorkingDaysConverter has to be initialized. For a list of TimeIntervalColumnHeaders the converter creates a "table" with integer that represents the age in days from the largest lower limit until the smallest upper limit of the timeIntervalColumnHeaders. This table is valid for a whole day until the converter is initialized with bigger limits.

Method Summary

Modifier and Type	Method and Description
int	convertDaysToWorkingDays(int ageInDays) Converts an integer, that represents the age in days, to the age in working days by using the table that was created by initialization.
long	convertWorkingDaysToDays(java.time.Instant startTime, long numberOfDays)
ArrayList<Integer>	convertWorkingDaysToDays(int ageInWorkingDays) Converts an integer, that represents the age in working days, to the age in days by using the table that was created by initialization.
List<java.time.LocalDate>	getCustomHolidays()
java.time.LocalDate	getEasterSunday(int year) Computes the date of Easter Sunday for a given year.
static DaysToWorkingDaysConverter	initialize(List<TimeIntervalColumnHeader> columnHeaders) Initializes the DaysToWorkingDaysConverter for a list of TimeIntervalColumnHeaders and the current day.
static DaysToWorkingDaysConverter	initialize(List<TimeIntervalColumnHeader> columnHeaders, java.time.Instant referenceDate) Initializes the DaysToWorkingDaysConverter for a list of TimeIntervalColumnHeaders and a referenceDate.
boolean	isGermanPublicHolidayEnabled()
static void	setCustomHolidays(List<java.time.LocalDate> holidays)
static void	setGermanPublicHolidaysEnabled(boolean germanPublicHolidaysEnabled)

Method Detail

initialize

public static DaysToWorkingDaysConverter initialize(List<TimeIntervalColumnHeader> columnHeaders)
                                             throws InvalidArgumentException

Initializes the DaysToWorkingDaysConverter for a list of TimeIntervalColumnHeaders and the current day. A new table is only created if there are bigger limits or the date has changed.

Parameters:

columnHeaders - a list of TimeIntervalColumnHeaders that determines the size of the table

Returns:

an instance of the DaysToWorkingDaysConverter

Throws:

InvalidArgumentException - thrown if columnHeaders is null

initialize

public static DaysToWorkingDaysConverter initialize(List<TimeIntervalColumnHeader> columnHeaders,
                                                    java.time.Instant referenceDate)
                                             throws InvalidArgumentException

Initializes the DaysToWorkingDaysConverter for a list of TimeIntervalColumnHeaders and a referenceDate. A new table is only created if there are bigger limits or the date has changed.

Parameters:

columnHeaders - a list of TimeIntervalColumnHeaders that determines the size of the table

referenceDate - a Instant that represents the current day of the table

Returns:

an instance of the DaysToWorkingDaysConverter

Throws:

InvalidArgumentException - thrown if columnHeaders or referenceDate is null

convertDaysToWorkingDays

public int convertDaysToWorkingDays(int ageInDays)

Converts an integer, that represents the age in days, to the age in working days by using the table that was created by initialization. If the age in days is beyond the limits of the table, the integer will be returned unchanged.

Parameters:

ageInDays - represents the age in days

Returns:

the age in working days

convertWorkingDaysToDays

public ArrayList<Integer> convertWorkingDaysToDays(int ageInWorkingDays)

Converts an integer, that represents the age in working days, to the age in days by using the table that was created by initialization. Because one age in working days could match to more than one age in days, the return value is a list of all days that match to the input parameter. If the age in working days is beyond the limits of the table, the integer will be returned unchanged.

Parameters:

ageInWorkingDays - represents the age in working days

Returns:

a list of age in days

convertWorkingDaysToDays

public long convertWorkingDaysToDays(java.time.Instant startTime,
                                     long numberOfDays)

getEasterSunday

public java.time.LocalDate getEasterSunday(int year)

Computes the date of Easter Sunday for a given year.

Parameters:

year - for which the date of Easter Sunday should be calculated

Returns:

the date of Easter Sunday for the given year

setCustomHolidays

public static void setCustomHolidays(List<java.time.LocalDate> holidays)

getCustomHolidays

public List<java.time.LocalDate> getCustomHolidays()

setGermanPublicHolidaysEnabled

public static void setGermanPublicHolidaysEnabled(boolean germanPublicHolidaysEnabled)

isGermanPublicHolidayEnabled

public boolean isGermanPublicHolidayEnabled()
