java.lang.Object org.joda.time.format.ISODateTimeFormat
public class ISODateTimeFormat
Factory that creates instances of DateTimeFormatter for the ISO8601 standard.
Datetime formatting is performed by the DateTimeFormatter
class.
Three classes provide factory methods to create formatters, and this is one.
The others are DateTimeFormat
and DateTimeFormatterBuilder
.
ISO8601 is the international standard for data interchange. It defines a
framework, rather than an absolute standard. As a result this provider has a
number of methods that represent common uses of the framework. The most common
formats are date
, time
, and dateTime
.
For example, to format a date time in ISO format:
DateTime dt = new DateTime(); DateTimeFormatter fmt = ISODateTimeFormat.dateTime(); String str = fmt.print(dt);
It is important to understand that these formatters are not linked to
the ISOChronology
. These formatters may be used with any
chronology, however there may be certain side effects with more unusual
chronologies. For example, the ISO formatters rely on dayOfWeek being
single digit, dayOfMonth being two digit and dayOfYear being three digit.
A chronology with a ten day week would thus cause issues. However, in
general, it is safe to use these formatters with other chronologies.
ISODateTimeFormat is threadsafe and immutable, and the formatters it returns are as well.

Method Detail 

public static DateTimeFormatter forFields(Collection<DateTimeFieldType> fields, boolean extended, boolean strictISO)
This method examines the fields provided and returns an ISOstyle formatter that best fits. This can be useful for outputting lesscommon ISO styles, such as YearMonth (YYYYMM) or MonthDay (MMDD).
The list provided may have overlapping fields, such as dayOfWeek and dayOfMonth. In this case, the style is chosen based on the following list, thus in the example, the calendar style is chosen as dayOfMonth is higher in priority than dayOfWeek:

strictISO
as true
.
This method can side effect the input collection of fields. If the input collection is modifiable, then each field that was added to the formatter will be removed from the collection, including any duplicates. If the input collection is unmodifiable then no side effect occurs.
This side effect processing is useful if you need to know whether all the fields were converted into the formatter or not. To achieve this, pass in a modifiable list, and check that it is empty on exit.
