com.fasterxml.jackson.databind.deser.NullValueProvider
-
Packages that use NullValueProvider Package Description com.fasterxml.jackson.databind Basic data binding (mapping) functionality that allows for reading JSON content into Java Objects (POJOs) and JSON Trees (JsonNode
), as well as writing Java Objects and trees as JSON.com.fasterxml.jackson.databind.deser Contains implementation classes of deserialization part of data binding.com.fasterxml.jackson.databind.deser.impl Contains those implementation classes of deserialization part of data binding that are not considered part of public or semi-public interfaces.com.fasterxml.jackson.databind.deser.std Contains public standard implementations of abstraction that Jackson uses.com.fasterxml.jackson.databind.ext Contains extended support for "external" packages: things that may or may not be present in runtime environment, but that are commonly enough used so that explicit support can be added. -
