所有已实现的接口:

Serialization

public class GenericProtobufSerialization
extends Object
implements Serialization

Currently, the Dubbo protocol / framework data, such as attachments, event data, etc., depends on business layer serialization protocol to do serialization before transmitted. That's a problem when using Protobuf as business serialization protocol, because Protobuf does not support raw java Object types, to solve it, we can use one of the following methods:

• 1. Package these data with Protobuf so that they can be serialized.
• 2. Separate the serialization of Dubbo protocol/framework and the service args (easy to cross-platform, cross-language serialization) to avoid the binding of this part and serialization protocol.

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

从接口复制的说明: Serialization

Get content type

指定者:

getContentType 在接口中 Serialization

返回:

content type
