How can I modify the pre serialization and post serialization values? I
need to transform some variables that are stored but I would like to do
this easily "inline"(would be cool to be able to provide a delegate to
do the transformations at the site of definition of the fields).
Use the "onSerializing" and "onSerialized" UDAs on a method.
"onSerializing" will be called before serializing and "onSerialized"
after serializing. Have a look at the unit tests [1].
Also, how does orange handle properties? Seems it just deals with fields
and ignores all functions(does not use getter and setter of properties).
This is valid, of course, just want to make sure. I still need to be
able to transform values pre and post though.
That is correct, it only (de)serializes fields. If you want to
(de)serialize proprieties, implement the "toData" and "fromData". See
the example in the wiki [2]. Note, by implementing these methods none of
the standard serialization will occur. If you want to serialize the
fields as well, you need to do that as well when implementing "toData"
and "fromData".
It's also possible to implement these "methods" in a non-intrusive way,
i.e. for customizing serialization of third party type [3].
