Method Detail

buildDateDPFacade

public static DateDPFacade buildDateDPFacade(double[] primitiveData)

factory method.

Parameters:

primitiveData - the date components. Can be either :

• Julian day 1950 : elapsed days, elapsed seconds since the 01/01/1950 at 00:00:00
• year, month, day (the time is set to 00:00:00)
• year, month, day, elapsed time from this date
• year, month, day, hour, minute, second
• year, month, day, hour, minute, second, elapsed time from this date

Returns:

a DateDPFacade instance

Since:

1.0

computeDeviationTo

public double computeDeviationTo(boolean absolute,
                                 DeviationProvider obj,
                                 boolean positive)

computes the deviation in seconds between the stored date and the given one.

Specified by:

computeDeviationTo in interface DeviationProvider

Parameters:

absolute - absolute or relative comparison

obj - the DeviationProvider that should be a DateDPFacade

positive - true if absolute value of deviations, false otherwise

Returns:

the deviation between the two values. The deviation is positive if the stored value is after than the one given, 0 if they are equal and negative if smaller.

Throws:

EphemerisComparatorRuntimeException - if the DeviationProvider is not of the correct type
