Does it automatically pick everything to serialize?
Yes.
How would you make it more selective?
It depends on what you want to do.
struct Me
{
int x;
int y;
}
serialize x but not y.
In this simple case you can do like this:
struct Me
{
int x;
int y;
mixin NonSerialized!(y);
}
Would you have to create a custom serializer?
No, not in this case. But it depends on what you want to do.
If so I would like to see an example with the custom serializer and
deserializer that only does the x.
Basic Example
Serialize Through Base Class
Register Serializer?
There is no register serializer example.
Yeah, I know.
277 private void serializeStruct (T) (T value, string key, Id id)
278 {
279 string type = T.stringof;
280
281 triggerEvents(serializing, value, {
282 archive.archiveStruct(type, key, id, {
283 if (type in serializers)
284 {
285 auto wrapper = getSerializerWrapper!(T)(type);
286 wrapper(value, this, key);
287 }
288
289 else
290 {
291 static if (isSerializable!(T))
292 value.toData(this, key);
293
294 else
295 objectStructSerializeHelper(value);
296 }
297 });
298 });
299 }
I assume that the wrapper is the custom serializer that can be registered.
Yes.
Then there is the toData that a struct can have, basically
member functions that do the serialization. Priority is
given to the registered serializer over the member functions.
Yes.
And the last one. ObjectStructSerializerHelper is more a default
serializer if none is registered or doesn't have the correct
isSerializable member functions.
ObjectStructSerializerHelper(T) (T .....)
Just browsing, I haven't downloaded anything.
You can have a look at "registerSerializer" and "registerDeserializer" here:
http://dl.dropbox.com/u/18386187/orange_docs/orange.serialization.Serializer.html
Most of the documented classes and methods contains examples.
There are basically three ways to customize the (de)serialization process:
* Using NonSerialized -
http://dl.dropbox.com/u/18386187/orange_docs/orange.serialization.Serializable.html
* Non-intrusive serialization (registerSerializer) -
http://dl.dropbox.com/u/18386187/orange_docs/orange.serialization.Serializer.html
* Intrusive serialization (toData) -
http://dl.dropbox.com/u/18386187/orange_docs/orange.serialization.Serializable.html
So in your example it would look something like this:
struct Me
{
int x;
int y;
}
auto archive = new XmlArchive!();
auto serializer = new Serializer(archive);
auto dg = (Me value, Serializer serializer, Data key) {
serializer.serialize(x, "x");
};
auto dg2 = (ref Me value, Serializer serializer, Data key) {
value.x = serializer.deserialize!(int)("x");
};
Serializer.registerSerializer!(Me)(dg);
Serializer.registerDeserializer!(Me)(dg2);
The above would be the non-intrusive example.
