CPCCompoundCalendarUnit

internal protocol CPCCompoundCalendarUnit : CPCCalendarUnit, BidirectionalCollection where Self.Element : CPCCalendarUnit, Self.Index == CPCCompoundCalendarUnitIndex

Protocol, implementing a collection of smaller units that are contained in this calendar unit.

  • Calculate all possible indices for a given compound unit.

    Declaration

    Swift

    static func indices(for value: BackingType, using calendar: Calendar) -> ContiguousArray<Int>

    Parameters

    value

    Backing value of a compound unit to perform calculations for.
    calendar

    Calendar to perform calculations with.

    Return Value

    All indices that are valid for compound unit that contains a date represented by given value.
