public Class BeanAsArrayBuilderDeserializer

Implements abstract com.fasterxml.jackson.databind.JsonDeserializer.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).

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

Parameters

p:JsonParser

Parsed used for reading JSON content

ctxt:DeserializationContext

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

Returns:Object

Deserialized value

Annotations

@Override

Overrides com.fasterxml.jackson.databind.JsonDeserializer.deserialize.

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

Alternate deserialization method (compared to the most commonly used, deserialize(JsonParser, DeserializationContext)), which takes in initialized value instance, to be configured and/or populated by deserializer. Method is not necessarily used (or supported) by all types (it will not work for immutable types, for obvious reasons): most commonly it is used for Collections and Maps. It may be used both with "updating readers" (for POJOs) and when Collections and Maps use "getter as setter".

Default implementation just throws UnsupportedOperationException, to indicate that types that do not explicitly add support do not necessarily support update-existing-value operation (esp. immutable types)

General version used when handling needs more advanced features.

Annotations

@Override

Overrides com.fasterxml.jackson.databind.deser.BeanDeserializerBase.supportsUpdate.

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

Introspection method that may be called to see whether deserializer supports update of an existing value (aka "merging") or not. Return value should either be Boolean#FALSE if update is not supported at all (immutable values); Boolean#TRUE if update should usually work (regular POJOs, for example), or null if this is either not known, or may sometimes work.

Information gathered is typically used to either prevent merging update for property (either by skipping, if based on global defaults; or by exception during deserializer construction if explicit attempt made) if Boolean#FALSE returned, or inclusion if Boolean#TRUE is specified. If "unknown" case (null returned) behavior is to exclude property if global defaults used; or to allow if explicit per-type or property merging is defined.

Default implementation returns null to allow explicit per-type or per-property attempts.

@Override

Implements abstract com.fasterxml.jackson.databind.deser.BeanDeserializerBase.unwrappingDeserializer.

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

Method that will return deserializer instance that is able to handle "unwrapped" value instances If no unwrapped instance can be constructed, will simply return this object as-is.

Default implementation just returns 'this' indicating that no unwrapped variant exists

Mutant factory method that custom sub-classes must override; not left as abstract to prevent more drastic backwards compatibility problems.
