## Uses of Class
com.fasterxml.jackson.databind.type.TypeBase

- Packages that use TypeBase
  Package | Description
  --- | ---
  com.fasterxml.jackson.databind.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).

    Subclasses of TypeBase in com.fasterxml.jackson.databind.type
    Modifier and Type | Class and Description
    --- | ---
    `class` | `ArrayType` Array types represent Java arrays, both primitive and object valued.
    `class` | `CollectionLikeType` Type that represents things that act similar to `Collection`; but may or may not be instances of that interface.
    `class` | `CollectionType` Type that represents Java Collection types (Lists, Sets).
    `class` | `MapLikeType` Type that represents Map-like types; things that consist of key/value pairs but that do not necessarily implement `Map`, but that do not have enough introspection functionality to allow for some level of generic handling.
    `class` | `MapType` Type that represents "true" Java Map types.
    `class` | `PlaceholderForType` Helper type used when introspecting bindings for already resolved types, needed for specialization.
    `class` | `ReferenceType` Specialized `SimpleType` for types that are referential types, that is, values that can be dereferenced to another value (or null), of different type.
    `class` | `ResolvedRecursiveType` Internal placeholder type used for self-references.
    `class` | `SimpleType` Simple types are defined as anything other than one of recognized container types (arrays, Collections, Maps).

    Constructors in com.fasterxml.jackson.databind.type with parameters of type TypeBase
    Constructor and Description
    `CollectionLikeType(TypeBase base, JavaType elemT)`
    `CollectionType(TypeBase base, JavaType elemT)`
    `MapLikeType(TypeBase base, JavaType keyT, JavaType valueT)`
    `MapType(TypeBase base, JavaType keyT, JavaType valueT)`
    `ReferenceType(TypeBase base, JavaType refType)` Constructor used when upgrading into this type (via `ReferenceType.upgradeFrom(com.fasterxml.jackson.databind.JavaType, com.fasterxml.jackson.databind.JavaType)`, the usual way for `ReferenceType`s to come into existence.
    `SimpleType(TypeBase base)` Simple copy-constructor, usually used when upgrading/refining a simple type into more specialized type.
    `TypeBase(TypeBase base)` Copy-constructor used when refining/upgrading type instances.
