# Abstract serialization services
-The serialization services are centered around the `auto_serializable` annotation,

the `Serializable` interface and the implementations of `Serializer` and `Deserializer`.
-## The `auto_serializable` annotation
+## The `serialize` annotation
-A class annotated with `auto_serializable` identifies it as a subclass of Serializable and

triggers the generation of customized serialization and deserialization services.

The deserialized instance will not be the same instance, but they should be equal.
So, in this case, we can compare both instances with `==` to test their equality.
-Some conditions applies to the classes that can be annotated as `auto_serializable`.
+Some conditions applies to the classes that can be annotated as `serialize`.
All attributes of the class must be serializable, runtime errors will be
raised when trying to serialize non-serializable attributes.
In the class `Person`, all attributes are typed with classes the standards library.
These common types are defined defined as serializable by this project.
-The attributes could also be typed with user-defined `auto_serializable`
+The attributes could also be typed with user-defined `serialize`
classes or any other subclass of `Serializable`.

-The `auto_serializable` applies only to the class definition,
-only attributes declared locally will be serialized.
-However, each definition of a class (a refinement or specialization)
-can declare `auto_serializable`.
+### Scope of the `serialize` annotation
+
+`serialize` can annotate class definitions, modules and attributes:
+
+* The annotation on a class applies only to the class definition,
+ only attributes declared locally will be serialized.
+ However, each definition of a class (a refinement or specialization) can be annotated with `serialize`.
+
+* A module declaration annotated with `serialize` states that all its class definitions
+ and locally declared attributes are serializable.
+
+ ~~~
+ module shared_between_clients is serialize
+ ~~~
+
+* Attribute annotated with `serialize` states that it is to be serialized, when the rest of the class does not.
+ The class will become subclass to `Serializable` but its attributes are not to be serialized by default.
+ Only the attributes with the `serialize` annotation will be serialized.
+
+ ~~~
+ # Only serialize the `name`
+ class UserCredentials
+ var name: String is serialize
+ var avatar_path: String = "/somepath/"+name is lazy
+ end
+ ~~~
+
+## The `noserialize` annotation
+
+The `noserialize` annotation mark an exception in a `serialize` module or class definition.
+
+* By default a module is `noserialize`. There is no need to declare it as such.
+
+* A class definition annotated with `noserialize` within a `serialize` module will not be made serializable.
+
+* A `noserialize` attribute within a class or module annotated with `serialize` will not serialize this attribute.
+ The class will still be made subclass of `Serializable` and it won't affect the other attributes.
+ The `noserialize` attribute will not be set at deserialization.
+ Usually, it will also be annotated with `lazy` to get its value by another mean after the object has been deserialized.
+
+ ~~~
+ # Once again, only serialize the `name`
+ class UserCredentials
+ serialize
+
+ var name: String
+ var avatar_path: String = "/somepath/"+name is noserialize, lazy

## Custom serializable classes
-The annotation `auto_serializable` should be enough for most cases,
+The annotation `serialize` should be enough for most cases,
but in some cases you need more control over the serialization process.
For more control, create a subclass to `Serializable` and redefine `core_serialize_to`.
### Example: the User class
-The following example cannot use the `auto_serializable` annotations
+The following example cannot use the `serialize` annotations
because some of the arguments to the `User` class need special treatment:
* The `name` attribute is perfectly normal, it can be serialized and deserialized
## Serialization services
-The `auto_serializable` annotation and the `Serializable` class are used on
+The `serialize` annotation and the `Serializable` class are used on
classes specific to the business domain.
To write (and read) instances of these classes to a persistent format
you must use implementations of `Serializer` and `Deserializer`.
* Not enough classes from the standard library are supported.
This only requires someone to actually code the support.
It should not be especially hard for most classes, some can
- simply declare the `auto_serializable` annotation.
+ simply declare the `serialize` annotation.
* A limitation of the Json parser prevents deserializing from files
with more than one object.
serialize a single object to each filesand use different instances of
serializer and deserializer each time.
-* The `auto_serializable` annotation does not handle very well
+* The `serialize` annotation does not handle very well
complex constructors. This could be improved in the compiler.
- For now, you may prefer to use `auto_serializable` on simple classes,
+ For now, you may prefer to use `serialize` on simple classes,
of by using custom `Serializable`.
* The serialization uses only the short name of a class, not its qualified name.
