org.springframework.binding.convert.converters.FormattedStringToNumber
A converter for common number types such as integers and big decimals. Allows the configuration of an explicit number pattern and locale. Works with a general purpose {@link DecimalFormat} instance returned by calling{@link NumberFormat#getInstance(Locale)} by default. This instance supports parsing any number type generally andwill not perform special type-specific logic such as rounding or truncation. Subclasses may override. Will coerse parsed Numbers to the desired numberClass as necessary. If type-coersion results in an overflow condition; for example, what can occur with a Long being coersed to a Short, an exception will be thrown. @see NumberFormat @see DecimalFormat @author Keith Donald
