public Class AtomicReferenceDeserializer

Overrides tools.jackson.databind.deser.std.ReferenceTypeDeserializer.getAbsentValue.

Overrides default tools.jackson.databind.deser.NullValueProvider.getAbsentValue.

Doc from tools.jackson.databind.ValueDeserializer.getAbsentValue.

Method called to determine placeholder value to be used for cases where no value was obtained from input but we must pass a value nonetheless: the common case is that of Creator methods requiring passing a value for every parameter. Usually this is same as getNullValue (which in turn is usually simply Java null), but it can be overridden for specific types: most notable scalar types must use "default" values.

This method needs to be called every time a determination is made.

Default implementation simply calls getNullValue and returns value.

Implements tools.jackson.databind.deser.NullValueProvider.getNullValue.

Doc from tools.jackson.databind.ValueDeserializer.getNullValue.

Method that can be called to determine value to be used for representing null values (values deserialized when JSON token is JsonToken#VALUE_NULL). Usually this is simply Java null, but for some types (especially primitives) it may be necessary to use non-null values.

This method may be called once, or multiple times, depending on what getNullAccessPattern() returns.

Default implementation simply returns null.

Implements abstract tools.jackson.databind.deser.std.ReferenceTypeDeserializer.getReferenced.

Doc from tools.jackson.databind.deser.std.ReferenceTypeDeserializer.getReferenced.

Method that may be called to find contents of specified reference, if any; or `null` if none. Note that method should never fail, so for types that use concept of "absence" vs "presence", `null` is to be returned for both "absent" and "reference to `null`" cases.

Overrides tools.jackson.databind.deser.std.ReferenceTypeDeserializer.supportsUpdate.

Doc from tools.jackson.databind.deser.std.ReferenceTypeDeserializer.supportsUpdate.

By default we assume that updateability mostly relies on value deserializer; if it supports updates, typically that's what matters. So let's just delegate.

Annotations

@Override

Implements abstract tools.jackson.databind.deser.std.ReferenceTypeDeserializer.updateReference.

Doc from tools.jackson.databind.deser.std.ReferenceTypeDeserializer.updateReference.

Method called in case of "merging update", in which we should try update reference instead of creating a new one. If this does not succeed, should just create a new instance.

@Override

Implements abstract tools.jackson.databind.deser.std.ReferenceTypeDeserializer.withResolved.

Doc from tools.jackson.databind.deser.std.ReferenceTypeDeserializer.withResolved.

Mutant factory method called when changes are needed; should construct newly configured instance with new values as indicated.
