Serialization

What gets serialized

• one needs to define properties to have them saved

What happens when saving

• saving creates a snapshot
• the serializer dissolves circular dependencies
• when serializing was successful, lively tries to deserialize the snapshot onces
• only if this works saving was successful
• Be aware of adding objects to the opened world!!

How to make custom behavior while saving

• some objects can not be saved by default
• for example weak maps
• you can use methods like __after_deserialize__ and similar as hooks
• if you want to save something circular like a morph structure in the snapshot customized use addFn('propertyName' , propertyValue) this will have a look on the dependencies and will dissolve the circular dependencies if necessary
• just adding snapshot.prop.propname = propValue will work but not check whether there are circular dependencies
