public Class AvroUntypedDeserializer

Overrides com.fasterxml.jackson.databind.deser.std.UntypedObjectDeserializer.deserialize.

Doc from com.fasterxml.jackson.databind.JsonDeserializer.deserialize.

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 or a FIELD_NAME.

The two possible input conditions for structured types result from polymorphism via fields. In the ordinary case, Jackson calls this method when it has encountered an OBJECT_START, and the method implementation must advance to the next token to see the first field name. If the application configures polymorphism via a field, then the object looks like the following.

      {
          "@class": "class name",
          ...
      }
  

       if (p.currentToken() == JsonToken.START_OBJECT) {
         p.nextToken();
       }
  

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).

Handling null values (JsonToken.VALUE_NULL)
: Note that this method is never called for the JSON null literal to avoid every deserializer from having to handle null values. Instead, the JsonDeserializer#getNullValue(DeserializationContext) method is called to produce a null value. To influence null handling, custom deserializers should override JsonDeserializer#getNullValue(DeserializationContext) and usually also JsonDeserializer#getNullAccessPattern().

Parameters

p:JsonParser

Parser used for reading JSON content

ctxt:DeserializationContext

Context that can be used to access information about this deserialization activity.

Returns:Object

Deserialized value

Overrides com.fasterxml.jackson.databind.deser.std.UntypedObjectDeserializer.deserializeWithType.

Doc from com.fasterxml.jackson.databind.deser.std.StdDeserializer.deserializeWithType.

Base implementation that does not assume specific type inclusion mechanism. Sub-classes are expected to override this method if they are to handle type information.

Parameters

typeDeserializer:TypeDeserializer

Doc from com.fasterxml.jackson.databind.JsonDeserializer.deserializeWithType.

Deserializer to use for handling type information

@Override

Overrides com.fasterxml.jackson.databind.deser.std.UntypedObjectDeserializer.resolve.

Implements com.fasterxml.jackson.databind.deser.ResolvableDeserializer.resolve.

Doc from com.fasterxml.jackson.databind.deser.ResolvableDeserializer.resolve.

Method called after deserializer instance has been constructed (and registered as necessary by provider objects), but before it has returned it to the caller. Called object can then resolve its dependencies to other types, including self-references (direct or indirect).

Parameters

ctxt:DeserializationContext

Context to use for accessing configuration, resolving secondary deserializers
