Question

我正在寻求帮助和建议，以帮助我在这个州机器模型允许客户在xtxUml餐厅订餐。我想显示如下图所示的模型，那么如何修复下面的代码呢？我得到的结果没有任何关联。感谢您的建议和帮助。

class RestuarantClasses extends ClassDiagram {
    @Spacing(0.5)
    @TopMost(People.class)
    @Row({Customer.class, Worker.class})
    @Column({People.class, Worker.class,Waiter.class})
    @Row({Cooker.class, Waiter.class, Cashier.class})
}
class RestuarantLayout extends Layout {}
}



class CustomerStates extends StateMachineDiagram<Customer> {
    @TopMost({Customer.OpenDoor.class})
    @Row({Customer.Waiting.class, Customer.StartSelection.class})
    @Row({Customer.SaladOrNoodle.class, Customer.OrderSteak.class})
    @Row({Customer.OrderNoodle.class, Customer.OrderSalad.class})

class L extends Layout {
}

enter image description here

Answer 1

尝试使用节点的下一个布局约束：

@Above(val = A.class, from = B.class)：方框A从B向北，紧挨着它。

@Right(val = A.class, from = B.class)：方框A从B向东，紧挨着它。

@Below(val = A.class, from = B.class)：方框A位于B的南边，紧挨着它。

@Left(val = A.class, from = B.class)：方框A位于B的西边，紧挨着它。

您的代码应如下所示：

@Above(val = OpenDoor.class, from = Waiting.class)
@Row({Waiting.class, StartSelection.class})
@Below(val= SaladOrNoodle.class, from = Waiting.class)
@Below(val=OrderNoodle.class, from = SaladOrNoodle.class)
@Right(val=OrderSalad.class, from = OrderNoodle.class)
@Right(val=OrderSteak.class, from = SaladOrNoodle.class)
@Below(val = Payment.class, from = OrderSalad.class)

Answer 2

我认为您的示例代码中存在一些拼写错误。 Layout类应该是图的内部类，如下所示：

    class RestuarantClasses extends ClassDiagram {
        @Spacing(0.5)
        @TopMost(People.class)
        @Row({Customer.class, Worker.class})
        @Column({People.class, Worker.class,Waiter.class})
        @Row({Cooker.class, Waiter.class, Cashier.class})
        class RestuarantLayout extends Layout {}
    }

在StateMachine描述中，您还必须指定框之间的垂直关系。该算法无法解析行的垂直对齐。

否则我认为您的图表说明没有问题。

注1：使用Above，Below，Left和Right，您可以表达方框的直接邻居。使用Row和Column是表达相同关系的便捷方式。

注2：您没有在任何地方写Payment州。默认情况下，图表描述中未包含的框不会出现在图表中。如果你想对盒子说什么，但是你想看到它使用Show注释。

你没有得到任何联想是非常有意义的。图表上显示的框之间的链接自动排列和可视化。

我尝试重新创建你的模型，它应该可以正常工作：

    package restaurant.model;

    class People;
    class Worker extends People;
    class Cooker extends Worker;
    class Cashier extends Worker;
    class Waiter extends Worker;

    class Customer extends People{
        initial OpenDoor;
        state Waiting;
        state StartSelection;
        state SaladOrNoodle;
        state OrderSteak;
        state OrderNoodle;
        state OrderSalad;
        state Payment;

        transition tr1{
            from OpenDoor;
            to Waiting;
        }

        transition startSelectionTr{
            from Waiting;
            to StartSelection;
            trigger StartSelectionSignal;
        }

        transition orderSteakTr{
            from StartSelection;
            to OrderSteak;
            trigger OrderSteakSignal;
        }

        transition orderSaladOrNoodleTr{
            from StartSelection;
            to SaladOrNoodle;
            trigger OrderSaladOrNoodleSignal;
        }

        transition orderSaladTr{
            from SaladOrNoodle;
            to OrderSalad;
            trigger OrderSaladSignal;
        }

        transition orderNoodleTr{
            from SaladOrNoodle;
            to OrderNoodle;
            trigger OrderNoodleSignal;
        }

        transition payTr1{
            from OrderNoodle;
            to Payment;
            trigger PaySignal;
        }

        transition payTr2{
            from OrderSteak;
            to Payment;
            trigger PaySignal;
        }

        transition payTr3{
            from SaladOrNoodle;
            to Payment;
            trigger PaySignal;
        }
    }

    signal StartSelectionSignal;
    signal OrderSteakSignal;
    signal OrderSaladOrNoodleSignal;
    signal OrderSaladSignal;
    signal OrderNoodleSignal;
    signal PaySignal;
