Class AbstractDeserializer

java.lang.Object
org.codehaus.jackson.map.JsonDeserializer<Object>
org.codehaus.jackson.map.deser.AbstractDeserializer

public class AbstractDeserializer extends JsonDeserializer<Object>
Deserializer only used as placeholder for abstract types during polymorphic type handling deserialization. If so, there is no real deserializer associated with nominal type, just TypeDeserializer; and any calls that do not pass such resolver will result in an error.

    • deserializeWithType

      public Object deserializeWithType(JsonParser jp, DeserializationContext ctxt, TypeDeserializer typeDeserializer) throws IOException, JsonProcessingException
      Description copied from class: JsonDeserializer
      Deserialization called when type being deserialized is defined to contain additional type identifier, to allow for correctly instantiating correct subtype. This can be due to annotation on type (or its supertype), or due to global settings without annotations.

      Default implementation may work for some types, but ideally subclasses should not rely on current default implementation. Implementation is mostly provided to avoid compilation errors with older code.

      Overrides:
      deserializeWithType in class JsonDeserializer<Object>
      Parameters:
      typeDeserializer - Deserializer to use for handling type information
      Throws:
      IOException
      JsonProcessingException
    • deserialize

      Description copied from class: JsonDeserializer
      Method that can be called to ask implementation to deserialize JSON content into the value type this serializer handles. Returned instance is to be constructed by method itself.

      Pre-condition for this method is that the parser points to the first event that is part of value to deserializer (and which is never JSON 'null' literal, more on this below): for simple types it may be the only value; and for structured types the Object start marker. Post-condition is that the parser will point to the last event that is part of deserialized value (or in case deserialization fails, event that was not recognized or usable, which may be the same event as the one it pointed to upon call).

      Note that this method is never called for JSON null literal, and thus deserializers need (and should) not check for it.

      Specified by:
      deserialize in class JsonDeserializer<Object>
      Parameters:
      jp - Parsed used for reading JSON content
      ctxt - Context that can be used to access information about this deserialization activity.
      Returns:
      Deserializer value
      Throws:
      IOException
      JsonProcessingException
