        Set the value of an element in an indexed property.

        NOTE Implementing methods must not call Bean.setIndexedProperty(), as doing so will cause a stack overflow. Implementing methods may call Beans.setIntrospectedIndexedProperty() instead.

        Specified by:
        setIndexedProperty in interface BeanInterface
        Parameters:
        key - name of the property
        index - index of the property element to change
        value - the value to set the property to

      • getIndexedProperty

        Get the value of an element in an indexed property.

        NOTE Implementing methods must not call Bean.getIndexedProperty(), as doing so will cause a stack overflow. Implementing methods may call Beans.getIntrospectedIndexedProperty() instead.

        Set the value of a property.

        NOTE Implementing methods must not call Bean.setProperty(), as doing so will cause a stack overflow. Implementing methods may call Beans.setIntrospectedProperty() instead.
