public final class IlvDateFormatFactory extends Object
IlvDateFormatFactory
class provides static factory methods that can be
used to create date format instances. The method signatures are consistent with those
provided by the standard DateFormat
class and the date formatters returned
are compatible. However, using the methods of this class provides several advantages
over using the standard DateFormat
:
IlvDateFormatFactory
returns instances of IlvDateFormat
,
instead of instances of SimpleDateFormat
. It automatically
uses an ICU SimpleDateFormat
instead of a
java.text.SimpleDateFormat
if appropriate. Also, if the
FastDateFormat
class from the
Jakarta Commons Lang package
is available on the classpath, IlvDateFormat
automatically takes
advantage of this to provide much faster formatted output.
IlvDateFormatFactory
implements caching techniques to provide a
significant speed improvement when creating date format instances.
