## Uses of Class
org.codehaus.jackson.map.type.ClassKey

- Packages that use ClassKey
  Package | Description
  --- | ---
  org.codehaus.jackson.jaxrs | Jackson-based JAX-RS provider that can automatically serialize and deserialize resources for JSON content type (MediaType).
  org.codehaus.jackson.map | 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`
  org.codehaus.jackson.map.deser | Contains implementation classes of deserialization part of data binding.
  org.codehaus.jackson.map.module | Package that contains classes and interfaces to help implement custom extension `Module`s (which are registered using `ObjectMapper.registerModule(org.codehaus.jackson.map.Module)`.
  org.codehaus.jackson.map.ser | Contains implementation classes of serialization part of data binding.
  org.codehaus.jackson.map.type | Package that contains concrete implementations of `JavaType`, as well as the factory (`TypeFactory`) for constructing instances from various input data types (like `Class`, `Type`) and programmatically (for structured types, arrays, `List`s and `Map`s).
  org.codehaus.jackson.map.util | Utility classes for Mapper package.

- - ### Uses of ClassKey in org.codehaus.jackson.jaxrs

    Fields in org.codehaus.jackson.jaxrs with type parameters of type ClassKey
    Modifier and Type | Field and Description
    --- | ---
    `protected HashSet<ClassKey>` | JacksonJsonProvider.`_cfgCustomUntouchables` Set of types (classes) that provider should ignore for data binding
    `static HashSet<ClassKey>` | JacksonJsonProvider.`_untouchables` Looks like we need to worry about accidental data binding for types we shouldn't be handling.
