return the current selection mode

setSelectionMode

void setSelectionMode(DateSelectionModel.SelectionMode mode)

Set the selection mode.

Parameters:

mode - new selection mode

getCalendar

Calendar getCalendar()

a clone of the calendar used by this model.

getFirstDayOfWeek

int getFirstDayOfWeek()

Gets what the first day of the week is; e.g., Calendar.SUNDAY in the U.S., Calendar.MONDAY in France. This is needed when the model selection mode is WEEK_INTERVAL_SELECTION. PENDING JW: move week-interval selection from JXMonthView into the model.

Sets what the first day of the week is. E.g., Calendar.SUNDAY in US, Calendar.MONDAY in France. Fires a DateSelectionEvent of type CALENDAR_CHANGED, if the value is different from the old.

The default value depends on the Calendar's default. PENDING JW: actually, it's a bound property. Use a propertyChangeListener?

Parameters:

firstDayOfWeek - The first day of the week.

void setMinimalDaysInFirstWeek(int minimalDays)

Sets the minimal number of days in the first week of the year. Fires a DateSelectionEvent of type CALENDAR_CHANGED, if the value is different from the old. The default value depends on the Calendar's default. PENDING JW: actually, it's a bound property. Use a propertyChangeListener?

Parameters:

minimalDays - the minimal number of days in the first week of the year.

See Also:

getMinimalDaysInFirstWeek(), Calendar

getTimeZone

TimeZone getTimeZone()

Returns the TimeZone of this model.

Returns:

the TimeZone of this model.

See Also:

setTimeZone(TimeZone)

setTimeZone

void setTimeZone(TimeZone timeZone)

Sets the TimeZone of this model. Fires a DateSelectionEvent of type CALENDAR_CHANGED if the new value is different from the old. The default value depends on the Calendar's default. PENDING JW: actually, it's a bound property. Use a propertyChangeListener?

Parameters:

timeZone - the TimeZone to use in this model, must not be null.

See Also:

getTimeZone()

getLocale

Locale getLocale()

Returns the Locale of this model's calendar.

Returns:

the Locale of this model's calendar.

setLocale

void setLocale(Locale locale)

Sets the Locale of this model's calendar. Fires a DateSelectionEvent of type CALENDAR_CHANGED if the new value is different from the old.

The default value is Locale.default().

PENDING JW: fall back to JComponent.getDefaultLocale instead? We use this with components anyway?

PENDING JW: actually, it's a bound property. Use a propertyChangeListener?

Parameters:

locale - the Locale to use. If null, the default Locale is used.

addSelectionInterval

void addSelectionInterval(Date startDate,
                          Date endDate)

Adds the specified selection interval to the selection model.

Parameters:

startDate - interval start date, must not be null

endDate - interval end date >= start date, must not be null

Throws:

NullPointerException - if any of the dates is null

setSelectionInterval

void setSelectionInterval(Date startDate,
                          Date endDate)

Sest the specified selection interval to the selection model.

Parameters:

startDate - interval start date, must not be null

endDate - interval end date >= start date, must not be null

Throws:

NullPointerException - if any of the dates is null

removeSelectionInterval

void removeSelectionInterval(Date startDate,
                             Date endDate)

Removes the specifed selection interval from the selection model. If the selection is changed by this method, it fires a DateSelectionEvent of type DATES_REMOVED.

Parameters:

startDate - interval start date, must not be null

endDate - interval end date >= start date, must not be null

Throws:

NullPointerException - if any of the dates is null

clearSelection

void clearSelection()

Clears any selection from the selection model. Fires an Event of type SELECTION_CLEARED if there had been a selection, does nothing otherwise.

getSelection

SortedSet<Date> getSelection()

Returns the current selection.

Returns:

sorted set of selected dates, guaranteed to be never null.

getFirstSelectionDate

Date getFirstSelectionDate()

Returns the earliest date in the selection or null if the selection is empty.

Returns:

the earliest date in the selection, or null if isSelectionEmpty.

See Also:

getLastSelectionDate(), getSelection(), isSelectionEmpty()

getLastSelectionDate

Date getLastSelectionDate()

Returns the latest date in the selection or null if the selection is empty.

Returns:

the lastest date in the selection, or null if isSelectionEmpty.

See Also:

getFirstSelectionDate(), getSelection(), isSelectionEmpty()

isSelected

boolean isSelected(Date date)

Returns true if the date specified is selected, false otherwise.

Note: it is up to implementations to define the exact notion of selected. It does not imply the exact date as given is contained the set returned from getSelection().

Parameters:

date - date to check for selection, must not be null

Returns:

true if the date is selected, false otherwise

Throws:

NullPointerException - if the date is null

getNormalizedDate

Date getNormalizedDate(Date date)

Returns a normalized Date as used by the implementation, if any. F.i. DaySelectionModel returns the start of the day in the model's calendar. If no normalization is applied, a clone of the Date itself is returned. The given Date is never changed.

The overall contract:

 if ((date != null) && isSelectable(date)) {
     setSelectionInterval(date, date);
     assertEquals(getNormalized(date), getFirstSelectionDate();
 }
 

Returns:

the date as it would be normalized before used in the model, must not be null.

Throws:

NullPointerException - if given date is null.

isSelectionEmpty

boolean isSelectionEmpty()

Returns true if the selection is empty, false otherwise.

Returns:

true if the selection is empty, false otherwise

getUnselectableDates

Returns a SortedSet of Dates that are unselectable.

Returns:

sorted set of dates

setUnselectableDates

void setUnselectableDates(SortedSet<Date> unselectableDates)

Sets a collection of dates which are not selectable.

Note: it is up to implementations to define the exact notion of unselectableDate. It does not imply the only the exact date as given is unselectable, it might have a period like "all dates on the same day". PENDING JW: any collection would do - why insist on a SortedSet?

Parameters:

unselectableDates - dates that are unselectable, must not be null and must not contain null dates.

isUnselectableDate

boolean isUnselectableDate(Date unselectableDate)

Returns true is the specified date is unselectable.

Parameters:

unselectableDate - the date to check for unselectability, must not be null.

Returns:

Return the lower bound date that is allowed to be selected for this model.

Returns:

lower bound date or null if not set

setLowerBound

void setLowerBound(Date lowerBound)

Set the lower bound date that is allowed to be selected for this model.

Parameters:

lowerBound - lower bound date or null if not set

setAdjusting
