接口 Serialization

@SPI(value="hessian2",
     scope=FRAMEWORK)
public interface Serialization

Serialization strategy interface that specifies a serializer. (SPI, Singleton, ThreadSafe) The default extension is hessian2 and the default serialization implementation of the dubbo protocol.

     e.g. <dubbo:protocol serialization="xxx" />
 

方法概要

修饰符和类型	方法	说明
ObjectInput	deserialize(URL url, InputStream input)	Get a deserialization implementation instance
String	getContentType()	Get content type
byte	getContentTypeId()	Get content type unique id, recommended that custom implementations use values different with any value of Constants and don't greater than ExchangeCodec.SERIALIZATION_MASK (31) because dubbo protocol use 5 bits to record serialization ID in header.
ObjectOutput	serialize(URL url, OutputStream output)	Get a serialization implementation instance

方法详细资料

getContentTypeId

byte getContentTypeId()

Get content type unique id, recommended that custom implementations use values different with any value of Constants and don't greater than ExchangeCodec.SERIALIZATION_MASK (31) because dubbo protocol use 5 bits to record serialization ID in header.

返回:

content type id

getContentType

String getContentType()

Get content type

返回:

content type

serialize

@Adaptive
ObjectOutput serialize(URL url,
                       OutputStream output)
                throws IOException

Get a serialization implementation instance

参数:

url - URL address for the remote service

output - the underlying output stream

返回:

serializer

抛出:

IOException

deserialize

@Adaptive
ObjectInput deserialize(URL url,
                        InputStream input)
                 throws IOException

Get a deserialization implementation instance

参数:

url - URL address for the remote service

input - the underlying input stream

返回:

deserializer

抛出:

IOException
