/**
|
||
|
|
* Methods for serializing/deserializing entry field values. Most widgets don't
|
||
|
|
* require this for their values, and those that do can typically serialize/
|
||
|
|
* deserialize on every change from within the widget. The serialization
|
||
|
|
* handlers here are for widgets whose values require heavy serialization that
|
||
|
|
* would hurt performance if run for every change.
|
||
|
|
|
||
|
|
* An example of this is the markdown widget, whose value is stored as a
|
||
|
|
* markdown string. Instead of stringifying on every change of that field, a
|
||
|
|
* deserialization method is registered from the widget's control module that
|
||
|
|
* converts the stored markdown string to an AST, and that AST serves as the
|
||
|
|
* widget model during editing.
|
||
|
|
*
|
||
|
|
* Serialization handlers should be registered for each widget that requires
|
||
|
|
* them, and the registration method is exposed through the registry. Any
|
||
|
|
* registered deserialization handlers run on entry load, and serialization
|
||
|
|
* handlers run on persist.
