Package org.apache.dubbo.common.serialize

Interface Serialization

All Known Implementing Classes:
DefaultSerializationExceptionWrapper
@SPI(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" />

  • Method Summary

    Modifier and Type
    Method
    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
