      • handleAction

        public java.util.Optional<java.lang.String> handleAction​(java.util.List<java.lang.Long> entryNumbers)
                                                          throws CartEntryActionException
        Description copied from interface: CartEntryActionHandler
        This method contains the logic of the action performed by the CartEntryActionHandler implementation. Even though the method CartEntryActionHandler.supports(CartEntryModel) prevents unsupported actions to be visible in the contextual menu, it is the responsibility of the handleAction method and the processes it calls to perform appropriate validations in case the action is called on a cart entry for which it should not.
        Specified by:
        handleAction in interface CartEntryActionHandler
        Parameters:
        entryNumbers - the cart entry number for which the action is executed.
        Returns:
        An empty optional to signal the controller to apply the default behaviour: redisplay the cart page with a success message. Otherwise return a custom redirect URL to navigate elsewhere upon the action completion. The expected url format is the format used as SpringMVC controller method return values.
        Throws:
        CartEntryActionException - when an error occurs.
      • getSuccessMessageKey

        public java.lang.String getSuccessMessageKey()
        Description copied from interface: CartEntryActionHandler

        Specified by:
        getSuccessMessageKey in interface CartEntryActionHandler
        Returns:
        the success message key.
      • getErrorMessageKey

        public java.lang.String getErrorMessageKey()
        Description copied from interface: CartEntryActionHandler
        Provides the key to the message that should be displayed when a CartEntryActionException is thrown.

      • supports

        public boolean supports​(CartEntryModel cartEntry)
        Description copied from interface: CartEntryActionHandler
        This method determines if the action should show or not in the cart entry tools menu. An action may not be supported by every cart entry and this is the method to override to make this decision. This method is intended to refine the contents of the contextual menu of a cart item. It is the responsibility of the method and the processes it calls to perform appropriate validations in case the action is called on a cart entry for which it should not.
        Specified by:
        supports in interface CartEntryActionHandler
        Parameters:
        cartEntry - the cart entry model.
        Returns:
        true if the cart entry supports the action, false otherwise.
