Class IlvDateFormatFactory

java.lang.Object

ilog.views.util.text.IlvDateFormatFactory

public final class IlvDateFormatFactory
extends Object

The 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.
