A marker interface, like Serializable or Cloneable may have a specific meaning to a Java Virtual Machine, or to a Java compiler, or to another Java class. In the particular case of deserializing a serialized Java object the meaning of the Serializable interface to a JVM is that it is possible that it can proceed to reconstruct that serialized object according to the Java Object Serialization Specification. What would a Java compiler do with the knowledge that a class implements the java.io.Serializable interface? What classes in the Java standard library could make use of the knowledge that another class implements the java.io.Serializable interface, and what could they do with this knowledge? > > so, its roughly like an IoC principle: "Instead of I define myself, you define me".
