```
Object output interface.

修饰符和类型	方法	说明
`default void`	`writeAttachments(Map<String,Object> attachments)`
`default void`	`writeEvent(Object data)`
`void`	`writeObject(Object obj)`	write object.
`default void`	`writeThrowable(Object obj)`	The following methods are customized for the requirement of Dubbo's RPC protocol implementation.

  - writeObject
```
void writeObject(Object obj)
          throws IOException
```
    write object.
    
    参数:
    
    obj - object.
    
    抛出:
    
    IOException
  - writeThrowable
```
default void writeThrowable(Object obj)
                     throws IOException
```
    The following methods are customized for the requirement of Dubbo's RPC protocol implementation. Legacy protocol implementation will try to write Map, Throwable and Null value directly to the stream, which does not meet the restrictions of all serialization protocols.
    See how ProtobufSerialization, KryoSerialization implemented these methods for more details.
    The binding of RPC protocol and biz serialization protocol is not a good practice. Encoding of RPC protocol should be highly independent and portable, easy to cross platforms and languages, for example, like the http headers, restricting the content of headers / attachments to Ascii strings and uses ISO_8859_1 to encode them. https://tools.ietf.org/html/rfc7540#section-8.1.2
    
    抛出:
    
    IOException
  - writeEvent
```
default void writeEvent(Object data)
                 throws IOException
```
    抛出:
    
    IOException
  - writeAttachments
```
default void writeAttachments(Map<String,Object> attachments)
                       throws IOException
```
    抛出:
    
    IOException
