public class 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 DecimalFormat
instance returned by calling
NumberFormat.getInstance(Locale)
by default. This instance supports parsing any number type generally and
will 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.
