 | Desde Flex 4.5, Adobe recomienda la utilización de la clase spark.validators.CurrencyValidator como una alternativa a esta clase. |
The CurrencyValidator class ensures that a String represents a valid currency expression. It can make sure the input falls within a given range (specified by
minValue and maxValue),
is non-negative (specified by allowNegative),
and does not exceed the specified precision. The
CurrencyValidator class correctly validates formatted and unformatted
currency expressions, e.g., "$12,345.00" and "12345".
You can customize the currencySymbol, alignSymbol,
thousandsSeparator, and decimalSeparator
properties for internationalization.
Sintaxis MXML

inherits all of the tag properties of its superclass,
and adds the following tag properties:

decimalPointCountError="The decimal separator can occur only once."

invalidCharError="The input contains invalid characters."
