| CurrencyValidator | | public class CurrencyValidator extends BigDecimalValidator (Code) | | Currency Validation and Conversion routines (java.math.BigDecimal).
This is one implementation of a currency validator that has the following features:
- It is lenient about the the presence of the currency symbol
- It converts the currency to a
java.math.BigDecimal
However 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 behaviour regarding the currency symbol.

| Constructor Summary | |
| public | CurrencyValidator()
Construct a strict instance. | | public | CurrencyValidator(boolean strict, boolean allowFractions)
Construct an instance with the specified strict setting. |
| Method Summary | |
| public static BigDecimalValidator | getInstance()
Return a singleton instance of this validator. | | 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. |
| CurrencyValidator | | public CurrencyValidator()(Code) | | Construct a strict instance.
|
| CurrencyValidator | | public CurrencyValidator(boolean strict, boolean allowFractions)(Code) | | Construct an instance with the specified strict setting.
Parameters:
strict - true if strict Format parsing should be used.
Parameters:
allowFractions - true if fractions areallowed or false if integers only. |
| getInstance | | public static BigDecimalValidator getInstance()(Code) | | Return a singleton instance of this validator.
A singleton instance of the CurrencyValidator. |
| parse | | protected Object parse(String value, Format formatter)(Code) | | Parse the value with the specified Format.
This implementation is lenient whether the currency symbol
is present or not. The default NumberFormat
behaviour 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.
Parameters:
value - The value to be parsed.
Parameters:
formatter - The Format to parse the value with. The parsed value if valid or null if invalid. |
