BloombergLP::bdlt::Calendar::weekendDaysTransition

Return the weekend‐days transition at the specified index in this calendar. For all index values from 0 to numWeekendDaysTransitions() ‐ 1 (inclusive), a unique weekend‐days transition is returned. The mapping of index to weekend‐days transition is invalidated when the set of weekend‐days transitions is modified by an invocation of addWeekendDay, addWeekendDays, addWeekendDaysTransition, intersectBusinessDays, intersectNonBusinessDays, removeAll, unionBusinessDays, or unionNonBusinessDays. The behavior is undefined unless 0 <= index < numWeekendDaysTransitions().
