derive

protected DayOfWeek derive(Calendrical calendrical)

Description copied from class: CalendricalRule

Derives the value of this rule from a calendrical.

This method derives the value for this field from other fields in the calendrical without directly querying the calendrical for the value.

For example, if this field is quarter-of-year, then the value can be derived from month-of-year.

The implementation only needs to derive the value based on its immediate parents. The use of Calendrical.get(CalendricalRule) will extract any further parents on demand.

A typical implementation of this method obtains the parent value and performs a calculation. For example, here is a simple implementation for the quarter-of-year field:

Integer moyVal = calendrical.get(ISOChronology.monthOfYearRule());
return (moyVal != null ? ((moyVal - 1) % 4) + 1) : null;

This method is designed to be overridden in subclasses. The subclass implementation must be thread-safe. The subclass implementation must not request the value of this rule from the specified calendrical, otherwise a stack overflow error will occur.

Overrides:

derive in class CalendricalRule<DayOfWeek>

Parameters:

calendrical - the calendrical to derive from, not null

Returns:

the derived value, null if unable to derive
