Method Details

on

public static SpanOfWeekdays on(Weekday day)

Creates a span of weekdays of only one day.

Parameters:

day - the single day of week which forms the span

Returns:

span of weekdays consisting of only given day

betweenMondayAndFriday

public static SpanOfWeekdays betweenMondayAndFriday()

Creates a typical working week from Monday to Friday.

Returns:

span of weekdays from Monday to Friday

between

public static SpanOfWeekdays between(Weekday start,
 Weekday end)

Creates a new span of weekdays.

It is possible to choose the same weekday for start and end. Then the resulting span will just consist of one single weekday.

Parameters:

start - the starting weekday

end - the ending weekday (inclusive)

Returns:

new span of weekdays

getStart

public Weekday getStart()

Obtains the start of this span of weekdays.

Returns:

the starting weekday

getEnd

public Weekday getEnd()

Obtains the end of this span of weekdays.

Returns:

the ending weekday

length

public int length()

Determines the count of days belonging to this span of weekdays.

Returns:

count of days in range 1-7

iterator

public Iterator<Weekday> iterator()

Specified by:

iterator in interface Iterable<Weekday>

formatter

public static ChronoFormatter<SpanOfWeekdays> formatter(String dynamicPattern,
 Locale locale)

Creates a formatter for given dynamic format pattern and locale.

The pattern is of dynamic type and only uses the symbol letters "S" (=START) and "E" (=END). The start must be present, but the end is optional. If the end is missing in parsing then it will be set to the start. The count of symbols controls the text width, and the output context can be set by an extra format attribute. Example:

     ChronoFormatter<SpanOfWeekdays> f =
          SpanOfWeekdays.formatter("SSSS[ 'to' EEEE]", Locale.ENGLISH);

     assertThat(f.format(SpanOfWeekdays.betweenMondayAndFriday()), is("Monday to Friday"));
     assertThat(f.parse("Sunday"), is(SpanOfWeekdays.on(Weekday.SUNDAY)));
 

Parameters:

dynamicPattern - format pattern

locale - the locale information

Returns:

new formatter
