Class FastDateFormat

java.lang.Object

org.pentaho.reporting.libraries.formatting.FastDateFormat

All Implemented Interfaces:

Serializable, Cloneable, FastFormat

public class FastDateFormat
extends Object
implements FastFormat

A wrapper around the java.text.SimpleDateFormat class. This wrapper limits the possible interactions with the wrapped format class and therefore we can treat the implementation as immutable.
