public class CurrencyValidator extends BigDecimalValidator
Currency Validation and Conversion routines (java.math.BigDecimal).
This is one implementation of a currency validator that has the following features:
java.math.BigDecimalHowever any of the number validators can be used for currency validation.
For example, if you wanted a currency validator that converts to a
java.lang.Integer then you can simply instantiate an
IntegerValidator with the appropriate format type:
... = new IntegerValidator(false, IntegerValidator.CURRENCY_FORMAT);
Pick the appropriate validator, depending on the type (e.g Float, Double, Integer, Long etc) you want the currency converted to. One thing to note - only the CurrencyValidator implements lenient behavior regarding the currency symbol.
CURRENCY_FORMAT, PERCENT_FORMAT, STANDARD_FORMAT| Constructor and Description |

CurrencyValidator()

public CurrencyValidator(boolean strict,

strict - true if strict
Format parsing should be used.allowFractions - true if fractions are
allowed or false if integers only.public static BigDecimalValidator getInstance()
protected Object parse(String value, Format formatter)
Parse the value with the specified Format.
This implementation is lenient whether the currency symbol
is present or not. The default NumberFormat
behavior is for the parsing to "fail" if the currency
symbol is missing. This method re-parses with a format
without the currency symbol if it fails initially.
