Interface Serialization

@SPI(value="hessian2")
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" />
 

Method Summary

Modifier and Type	Method and Description
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

Method Detail
