Class FastDecimalFormat

java.lang.Object

org.pentaho.reporting.libraries.formatting.FastDecimalFormat

All Implemented Interfaces:

Serializable, Cloneable, FastFormat

public class FastDecimalFormat
extends Object
implements FastFormat

A wrapper around the java.text.DecimalFormat class. This wrapper limits the possible interactions with the wrapped format class and therefore eliminates the need to clone the choice format whenever the wrapper is cloned.
