## Package com.fasterxml.jackson.core

Main public API classes of the core streaming JSON processor: most importantly `JsonFactory` used for constructing JSON parser (`JsonParser`) and generator (`JsonParser`) instances.

See:
Description

Interface Summary
FormatSchema | Simple tag interface used to mark schema objects that are used by some `JsonParser` and `JsonGenerator` implementations to further specify structure of expected format.
PrettyPrinter | Interface for objects that implement pretty printer functionality, such as indentation.
SerializableString | Interface that defines how Jackson package can interact with efficient pre-serialized or lazily-serialized and reused String representations.
TreeNode | Marker interface used to denote JSON Tree nodes, as far as the core package knows them (which is very little): mostly needed to allow `ObjectCodec` to have some level of interoperability.
Versioned | Interface that those Jackson components that are explicitly versioned will implement.

Class Summary
Base64Variant | Abstract base class used to define specific details of which variant of Base64 encoding/decoding is to be used.
Base64Variants | Container for commonly used Base64 variants.
JsonFactory | The main factory class of Jackson package, used to configure and construct reader (aka parser, `JsonParser`) and writer (aka generator, `JsonGenerator`) instances.
JsonGenerator | Base class that defines public API for writing JSON content.
JsonLocation | Object that encapsulates Location information used for reporting parsing (or potentially generation) errors, as well as current location within input streams.
JsonParser | Base class that defines public API for reading JSON content.
JsonStreamContext | Shared base class for streaming processing contexts used during reading and writing of Json content using Streaming API.
ObjectCodec | Abstract class that defines the interface that `JsonParser` and `JsonGenerator` use to serialize and deserialize regular Java objects (POJOs aka Beans).
Version | Object that encapsulates versioning information of a component.

Enum Summary
JsonEncoding | Enumeration that defines legal encodings that can be used for JSON content, based on list of allowed encodings from JSON specification.
JsonFactory.Feature | Enumeration that defines all on/off features that can only be changed for `JsonFactory`.
JsonGenerator.Feature | Enumeration that defines all togglable features for generators.
JsonParser.Feature | Enumeration that defines all on/off features for parsers.
JsonParser.NumberType | Enumeration of possible "native" (optimal) types that can be used for numbers.
JsonToken | Enumeration for basic token types used for returning results of parsing JSON content.

Exception Summary
JsonGenerationException | Exception type for exceptions during JSON writing, such as trying to output content in wrong context (non-matching end-array or end-object, for example).
JsonParseException | Exception type for parsing problems, used when non-well-formed content (content that does not conform to JSON syntax as per specification) is encountered.
JsonProcessingException | Intermediate base class for all problems encountered when processing (parsing, generating) JSON content that are not pure I/O problems.

## Package com.fasterxml.jackson.core Description

Main public API classes of the core streaming JSON processor: most importantly `JsonFactory` used for constructing JSON parser (`JsonParser`) and generator (`JsonParser`) instances.

Public API of the higher-level mapping interfaces ("Mapping API") is found from the "jackson-databind" bundle, except for following base interfaces that are defined here:

- `TreeNode` is included within Streaming API to support integration of the Tree Model (which is based on `JsonNode`) with the basic parsers and generators (iff using mapping-supporting factory: which is part of Mapping API, not core)
- `ObjectCodec` is included so that reference to the object capable of serializing/deserializing Objects to/from JSON (usually, `com.fasterxml.jackson.databind.ObjectMapper`) can be exposed, without adding direct dependency to implementation.
