Class CustomNumberEditor

java.lang.Object
  java.beans.PropertyEditorSupport
      org.springframework.beans.propertyeditors.CustomNumberEditor

All Implemented Interfaces:

java.beans.PropertyEditor

public class CustomNumberEditor

extends java.beans.PropertyEditorSupport

Property editor for any Number subclass like Integer, Long, Float, Double. Uses a given NumberFormat for (locale-specific) parsing and rendering.

This is not meant to be used as system PropertyEditor but rather as locale-specific number editor within custom controller code, to parse user-entered number strings into Number properties of beans, and render them in the UI form.

In web MVC code, this editor will typically be registered with binder.registerCustomEditor calls in an implementation of BaseCommandController's initBinder method.
