# jackson-databind 2.11.0.rc1 API

Packages
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.annotation | Annotations that directly depend on classes in databinding bundle (not just Jackson core) and cannot be included in Jackson core annotations package (because it cannot have any external dependencies).
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.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.exc |
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.
com.fasterxml.jackson.databind.introspect | Functionality needed for Bean introspection, required for detecting accessors and mutators for Beans, as well as locating and handling method annotations.
com.fasterxml.jackson.databind.json |
com.fasterxml.jackson.databind.jsonFormatVisitors | Classes used for exposing logical structure of POJOs as Jackson sees it, and exposed via `ObjectMapper.acceptJsonFormatVisitor(Class, JsonFormatVisitorWrapper)` and `ObjectMapper.acceptJsonFormatVisitor(com.fasterxml.jackson.databind.JavaType, JsonFormatVisitorWrapper)` methods.
com.fasterxml.jackson.databind.jsonschema | Classes needed for JSON schema support (currently just ability to generate schemas using serialization part of data mapping)
com.fasterxml.jackson.databind.jsontype | Package that contains interfaces that define how to implement functionality for dynamically resolving type during deserialization.
com.fasterxml.jackson.databind.jsontype.impl | Package that contains standard implementations for `TypeResolverBuilder` and `TypeIdResolver`.
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)`.
com.fasterxml.jackson.databind.node | Contains concrete `JsonNode` implementations Jackson uses for the Tree model.
com.fasterxml.jackson.databind.ser | Contains implementation classes of serialization part of data binding.
com.fasterxml.jackson.databind.ser.impl | Contains implementation classes of serialization part of data binding.
com.fasterxml.jackson.databind.ser.std |
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).
com.fasterxml.jackson.databind.util | Utility classes for Mapper package.
