Class FormattingDecimalConvertor

java.lang.Object

All Implemented Interfaces:

Convertor

Direct Known Subclasses:

FormattingDoubleConvertor, FormattingFloatConvertor, FormattingIntegerConvertor, FormattingLongConvertor

public class FormattingDecimalConvertor
extends Object
implements Convertor

A Convertor for BigDecimals backed by the DecimalFormat class.

It can be configured to use one of these variants: integer, number, currency or percent.

Alternatively, a formatting pattern can be used. This can either be a locale-dependent or locale-independent formatting pattern. When looking up a formatting pattern, a mechansim similar to resource bundle lookup is used. Suppose the locale is nl-BE, then first a formatting pattern for nl-BE will be sought, then one for nl, and if that is not found, finally the locale-independent formatting pattern will be used.
