Class FastDateFormat

java.lang.Object

java.text.Format

java.text.DateFormat

org.tinygroup.jspengine.util.FastDateFormat

All Implemented Interfaces:

Serializable, Cloneable

public class FastDateFormat
extends DateFormat

Fast date formatter that caches recently formatted date information and uses it to avoid too-frequent calls to the underlying formatter. Note: breaks fieldPosition param of format(Date, StringBuffer, FieldPosition). If you care about the field position, call the underlying DateFormat directly.
