Caller then asks serializer to serialize a 然后调用方让序列化程序序列化a :
Specifies that a serializer should be allowed to serialize the value of the property 指定应该允许序列化程序序列化属性( property )的值。
At this stage , the message has already been serialized by the formatter and cannot be modified 在这一阶段,消息已经被格式化程序序列化且不能修改。
In addition , messages serialized by the xml formatter do not necessarily have to be deserialized at all 另外,由xml格式化程序序列化的消息不一定非要反序列化。
Another advantage is that messages serialized with this formatter do not have to be deserialized by the same formatter object 另一个优点是使用此格式化程序序列化的消息不必用同一个格式化程序对象反序列化。
