Expression.accept介绍

[英]This method must be implemented by all concrete classes that implement this interface. It should call a visit method on the visitor that has one parameter, which has the type of the concrete implementing class.

See the Visitor Pattern for more details.
[中]此方法必须由实现此接口的所有具体类实现。它应该对具有一个参数的访问者调用一个visit方法，该参数具有具体实现类的类型。
有关更多详细信息，请参见访问者模式。
