## Uses of Interface
com.fasterxml.jackson.databind.deser.KeyDeserializers

- Packages that use KeyDeserializers
  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.cfg | Package that contains most of configuration-related classes; exception being couple of most-commonly used configuration things (like Feature enumerations) that are at the main level (`com.fasterxml.jackson.databind`).
  com.fasterxml.jackson.databind.deser | Contains implementation classes of deserialization part of data binding.
  com.fasterxml.jackson.databind.deser.std | Contains public standard implementations of abstraction that Jackson uses.
  com.fasterxml.jackson.databind.module | Package that contains classes and interfaces to help implement custom extension `Module`s (which are registered using `ObjectMapper.registerModule(com.fasterxml.jackson.databind.Module)`.

- - ### Uses of KeyDeserializers in com.fasterxml.jackson.databind

    Methods in com.fasterxml.jackson.databind with parameters of type KeyDeserializers
    Modifier and Type | Method and Description
    --- | ---
    `void` | Module.SetupContext.`addKeyDeserializers(KeyDeserializers s)` Method that module can use to register additional deserializers to use for handling Map key values (which are separate from value deserializers because they are always serialized from String values)

  - ### Uses of KeyDeserializers in com.fasterxml.jackson.databind.cfg

    Fields in com.fasterxml.jackson.databind.cfg declared as KeyDeserializers
    Modifier and Type | Field and Description
    --- | ---
    `protected KeyDeserializers[]` | DeserializerFactoryConfig.`_additionalKeyDeserializers` List of providers for additional key deserializers, checked before considering standard key deserializers.
    `protected static KeyDeserializers[]` | DeserializerFactoryConfig.`DEFAULT_KEY_DESERIALIZERS` By default we plug default key deserializers using as "just another" set of of key deserializers.

    Methods in com.fasterxml.jackson.databind.cfg that return types with arguments of type KeyDeserializers
    Modifier and Type | Method and Description
    --- | ---
    `Iterable<KeyDeserializers>` | DeserializerFactoryConfig.`keyDeserializers()`

    Methods in com.fasterxml.jackson.databind.cfg with parameters of type KeyDeserializers
    Modifier and Type | Method and Description
    --- | ---
    `DeserializerFactoryConfig` | DeserializerFactoryConfig.`withAdditionalKeyDeserializers(KeyDeserializers additional)` Fluent/factory method used to construct a configuration object that has same key deserializer providers as this instance, plus one specified as argument.

    Constructors in com.fasterxml.jackson.databind.cfg with parameters of type KeyDeserializers
    Constructor and Description
    `DeserializerFactoryConfig(Deserializers[] allAdditionalDeserializers, KeyDeserializers[] allAdditionalKeyDeserializers, BeanDeserializerModifier[] modifiers, AbstractTypeResolver[] atr, ValueInstantiators[] vi)` Copy-constructor that will create an instance that contains defined set of additional deserializer providers.

    Modifier and Type | Method and Description
    --- | ---
    `abstract DeserializerFactory` | DeserializerFactory.`withAdditionalKeyDeserializers(KeyDeserializers additional)` Convenience method for creating a new factory instance with additional `KeyDeserializers`.
    `DeserializerFactory` | BasicDeserializerFactory.`withAdditionalKeyDeserializers(KeyDeserializers additional)` Convenience method for creating a new factory instance with additional `KeyDeserializers`.

    Modifier and Type | Class and Description
    --- | ---
    `class` | `SimpleKeyDeserializers` Simple implementation `KeyDeserializers` which allows registration of deserializers based on raw (type erased class).
