If you want to change an immutable object, you don't - you create a new object with the changed value and point your reference to it.
如果您想要改变一个不可变对象的话，您不会改变它，而是使用修改后的值来创建一个新的对象，并把您的引用指向它。
In addition, these simple built-in types are immutable, which means you can't change an object's value after the object has been created.
另外，这些简单的内置类型是不可改变的，这意味着：创建对象之后，您无法更改对象的值。
If the USN value sent does not match the USN value currently persisted in the repository, the ce server knows that a change was made (by some other caller) since the object was fetched.
如果发送的US n值与储存库中储存的值不匹配，CE服务器就知道已经(由其他调用方)进行了更新，因此该对象已被获取。
An action typically results in a change in the state of the system, and can be realized by sending a message to an object or modifying a link or a value of an attribute.
一个动作典型地导致系统状态的变化，并且能通过给一个对象发送消息或者通过修改一个链接和属性值而实现。
Override this method if the type you want to convert must re-create the object to change its value.
如果要转换的类型必须重新创建该对象才能更改其值，则重写此方法。
A value of -1 flips the scaled object but does not change its vertical size.
如果值为—1，则翻转缩放对象，但不更改其垂直大小。
When still object detection is a less requirement, configure this parameter to a higher value to increase background learning speed to prevent scene-change induced error rates.
若无侦测静止物件的需求，较高的学习速度可减少场景变化所造成的误判。
A value of -1 flips the scaled object but does not change its horizontal size.
值- 1会翻转缩放的物件，但是不会变更它的水平大小。
