Examples of org.springframework.beans.propertyeditors.CustomNumberEditor

org.springframework.beans.propertyeditors.CustomNumberEditor
Property editor for any Number subclass such as Short, Integer, Long, BigInteger, Float, Double, BigDecimal. Can use a given NumberFormat for (locale-specific) parsing and rendering, or alternatively the default decode / valueOf / toString methods.
This is not meant to be used as system PropertyEditor but rather as locale-specific number editor within custom controller code, parsing user-entered number strings into Number properties of beans and rendering them in the UI form.
In web MVC code, this editor will typically be registered with binder.registerCustomEditor calls in a custom initBinder method. @author Juergen Hoeller @since 06.06.2003 @see java.lang.Number @see java.text.NumberFormat @see org.springframework.validation.DataBinder#registerCustomEditor @see org.springframework.web.servlet.mvc.BaseCommandController#initBinder
