类型可以是基元，如字符串(SDO称它们为“数据类型”，并定义了一个映射到php类型的集合)或复杂类型来代表序列或地址(SDO称它们为数据对象类型)。
Types can be primitives, such as string (SDO calls these "data types" and defines a set mapped to PHP types), or complex types to represent an order or address (SDO calls these data object types).
然后，调用友元函数spacefriend并将类对象的地址作为其参数传递。然后调用template函数，先使用整数类型，然后使用浮点数据类型。
It then calls the friend function spacefriend and passes the class object address as its argument, and calls the template function, beginning with integer types and then floating data types.
在应用程序中，以address类型的对象引用所有对象，而不必处理两种类型的地址。
In your application, refer to all objects as objects of type address, instead of having to deal with both types of addresses.
AddressDisplay对象有两部分：地址类型和一个格式化的地址字符串。
The AddressDisplay object has two parts: the type of address and a formatted address string.
装箱的值类型也有相同的地址作为对象的实际值类型？
Does the boxed value type have the same address as the actual value type in the object?
将来自当前地址头的信息项反序列化为具有指定类型的对象，该对象使用指定格式化程序对此信息进行序列化。
Deserializes the information item from the current address header to an object of a specified type that USES a specified formatter to serialize this information.
不属于位域的两个对象可能拥有相同的地址（如果一个对象是另一个对象的子对象，或者至少有一个是空的基类子对象，并且他们的类型不同）； 否则，他们应该在不同的地址上。
Two objects that are not bit-fields may have the same address if one is a subobject of the other, or if at least one is a base class subobject of zero size and they are of different types;
