Class YearlyCalendar

java.lang.Object
  java.util.Observable
      mvp.Model
          caltool.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.

update

public void update(java.util.Observable o,
                   java.lang.Object arg)

Update this' data based on the current selection in the current calendar. For initial testing purposes, the fixed year of 1998 is created, details of which are shown in Section 2.3.1.4 of the requirements. In the refined implementation, the calendar db will be consulted to obtain the actual information for the currently selected year.
