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.

    • _acceptsAllUnwrapped

      protected final boolean _acceptsAllUnwrapped
      Flag that indicates that we cannot tell from property names alone whether an incoming property is "unwrapped": either some unwrapped deserializer has an "any setter" (see JsonAnySetter), or is "opaque" -- declares no property names (via ValueDeserializer.collectAllPropertyNamesTo(java.util.Set<java.lang.String>)), as is the case for custom unwrapping deserializers that capture arbitrary fields. When set, all otherwise-unrecognized properties are routed to the unwrapped deserializers -- as was the case before [databind#650].

      public Object processUnwrapped(JsonParser originalParser, DeserializationContext ctxt, Object bean, TokenBuffer buffered, boolean hasUnwrappedContent)
      Processes unwrapped properties from the buffered token stream.
      Parameters:
      originalParser - Parser from which input was originally read
      ctxt - Deserialization context
      bean - the target value object
      buffered - the token buffer containing the JSON tokens to deserialize

      the bean with unwrapped properties set

    • creatorParamName

      public static PropertyName creatorParamName(int index)
      Generates a placeholder name for creator properties that don't have a name, but are marked with `@JsonUnwrapped` annotation.

      2.19

    • hasUnwrappedProperty

      public boolean hasUnwrappedProperty(String propName)
      Method that checks if the given property name belongs to any unwrapped property.
      Parameters:
      propName - Property name to check
      Returns:
      true if name is recognized by an unwrapped deserializer (or if any of them has "any setter")

      public void collectUnwrappedPropertyNamesTo(Set<String> names)
