方法详细资料

readObject

@Deprecated
Object readObject()
           throws IOException,
                  ClassNotFoundException

已过时。

Consider use readObject(Class) or readObject(Class, Type) where possible

返回:

object

抛出:

IOException - if an I/O error occurs

ClassNotFoundException - if an ClassNotFoundException occurs

readObject

<T> T readObject(Class<T> cls)
          throws IOException,
                 ClassNotFoundException

read object

参数:

cls - object class

返回:

object

抛出:

IOException - if an I/O error occurs

ClassNotFoundException - if an ClassNotFoundException occurs

readObject

<T> T readObject(Class<T> cls,
                 Type type)
          throws IOException,
                 ClassNotFoundException

read object

参数:

cls - object class

type - object type

返回:

object

抛出:

IOException - if an I/O error occurs

ClassNotFoundException - if an ClassNotFoundException occurs

readThrowable

default Throwable readThrowable()
                         throws IOException,
                                ClassNotFoundException

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

ClassNotFoundException

readEvent

default Object readEvent()
                  throws IOException,
                         ClassNotFoundException

抛出:

IOException

ClassNotFoundException

readAttachments

default Map<String,Object> readAttachments()
                                          throws IOException,
                                                 ClassNotFoundException

抛出:

IOException

ClassNotFoundException
