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

Packages that use KeyDeserializers
Package | Description
--- | ---
com.fasterxml.jackson.databind | Contains basic mapper (conversion) functionality that allows for converting between regular streaming json content and Java objects (beans or Tree Model: support for both is via `ObjectMapper` class, as well as convenience methods included in `JsonParser`
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.

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

Methods in com.fasterxml.jackson.databind.deser with parameters of type KeyDeserializers
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`.

### Uses of KeyDeserializers in com.fasterxml.jackson.databind.deser.std

Classes in com.fasterxml.jackson.databind.deser.std that implement KeyDeserializers
Modifier and Type | Class and Description

`class` | `StdKeyDeserializers` Helper class used to contain simple/well-known key deserializers.

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

Classes in com.fasterxml.jackson.databind.module that implement KeyDeserializers
Modifier and Type | Class and Description
--- | ---
`class` | `SimpleKeyDeserializers` Simple implementation `KeyDeserializers` which allows registration of deserializers based on raw (type erased class).
