org.springframework.beans.propertyeditors
Class CustomBooleanEditor

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

All Implemented Interfaces:

PropertyEditor

---

public class CustomBooleanEditor
extends PropertyEditorSupport

Property editor for Boolean/boolean properties.

This is not meant to be used as system PropertyEditor but rather as locale-specific Boolean editor within custom controller code, to parse UI-caused boolean strings into boolean properties of beans and check 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.
