Description copied from class: JsonDeserializer

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.

Since version 2.6 (in which the context argument was added), call is expected to be made each and every time a null token needs to be handled.

Default implementation simply returns null.

Overrides:

getNullValue in class JsonDeserializer<T>

Throws:

JsonMappingException

getNullValue

@Deprecated
public final T getNullValue()

Deprecated.

Overrides:

getNullValue in class JsonDeserializer<T>
