Examples of java.io.ObjectInputStream

java.io.ObjectInputStream
An ObjectInputStream can be used to load Java objects from a stream where the objects were saved using an ObjectOutputStream. Primitive data (ints, bytes, chars, etc) can also be loaded if the data was saved as primitive types as well. It is invalid to attempt to read an object as primitive data. @see ObjectOutputStream @see ObjectInput @see Serializable @see Externalizable

        m.writeExternal(msg_out);
        msg_out.flush();
        msg_out.close();
        byte[] data=msg_data.toByteArray();
        ByteArrayInputStream msg_in_data=new ByteArrayInputStream(data);
        ObjectInputStream msg_in=new ObjectInputStream(msg_in_data);
        MethodCall m2=new MethodCall();
        m2.readExternal(msg_in);
        System.out.println(m2.getName());
        System.out.println(m2.getArgs().length);
    }
