Class UnwrappedPropertyHandler

java.lang.Object

tools.jackson.databind.deser.impl.UnwrappedPropertyHandler

public class UnwrappedPropertyHandler
extends Object

Object that is responsible for handling acrobatics related to deserializing "unwrapped" values; sets of properties that are embedded (inlined) as properties of parent JSON object.
