[Java] Class WithSerialId

java.lang.Object
  groovyx.gpars.serial.WithSerialId

All Implemented Interfaces:

java.io.Serializable

public abstract class WithSerialId
extends java.lang.Object

Base class for objects which can be exposed to remote nodes via serialization.

Main concept is following: - each object belongs to some LocalHost - every object can be exposed to any RemoteHost - on remote host object is represented by proxy usually called remote object - for serialization we use writeReplace method, which creates special handle to be serialized instead of the object - for deserialization handle's readResolve method creates remote object (proxy)

See java.io.Serializable for detailed description how methods writeReplace & readResolve works.

It is very important to know that (de)serialization never happens by itself but always happens in context of RemoteHost and (

LocalHost}. Such context is used for right resolution/transformation of objects
