Class YearlyCalendar

java.lang.Object

java.util.Observable

mvp.Model

caltool.model.view.YearlyCalendar

All Implemented Interfaces:

java.io.Serializable

public class YearlyCalendar
extends mvp.Model

A YearlyCalendar contains a small view for each month, organized in four 3-month rows. The primarly access interface is through getFirstDay and getNumberOfDays methods. These methods take a month name and deliver the first day of that month and its number of days, respectively.

Since the yearly calendar contains no scheduled data itself, there is no need for any model data storage here. Rather, the access methods consult the calendar db to dynamically generate the date number values for each month.
