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

请参阅: 说明

接口概要

接口	说明
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.
Versioned	Interface that those Jackson components that are explicitly versioned will implement.

类概要

类	说明
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.
JsonNode	Base class for all JSON nodes, which form the basis of JSON Tree Model that Jackson implements.
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 version information of a component, and is return by Versioned.version().

枚举概要

枚举	说明
JsonEncoding	Enumeration that defines legal encodings that can be used for JSON content, based on list of allowed encodings from JSON specification.
JsonGenerator.Feature	Enumeration that defines all togglable features for generators.
JsonParser.Feature	Enumeration that defines all togglable 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.

异常错误概要

异常错误	说明
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.

程序包org.codehaus.jackson的说明

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 under org.codehaus.jackson.map and not included here, except for following base interfaces:

• JsonNode 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, ObjectMapper) can be exposed, without adding direct dependency to implementation.
