## Uses of Interface
com.fasterxml.jackson.core.Versioned

Packages that use Versioned
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 (`JsonGenerator`) instances.
com.fasterxml.jackson.core.base: Base classes used by concrete Parser and Generator implementations; contain functionality that is not specific to JSON or input abstraction (byte vs char).
com.fasterxml.jackson.core.filter
com.fasterxml.jackson.core.json: JSON-specific parser and generator implementation classes that Jackson defines and uses.
com.fasterxml.jackson.core.json.async: Non-blocking ("async") JSON parser implementation.
com.fasterxml.jackson.core.util: Utility classes used by Jackson Core functionality.

### Uses of Versioned in com.fasterxml.jackson.core

Classes in com.fasterxml.jackson.core that implement Versioned
`class` `JsonFactory` The main factory class of Jackson package, used to configure and construct reader (aka parser, `JsonParser`) and writer (aka generator, `JsonGenerator`) instances.
`class` `JsonGenerator` Base class that defines public API for writing JSON content.
`class` `JsonParser` Base class that defines public API for reading JSON content.
`class` `ObjectCodec` Abstract class that defines the interface that `JsonParser` and `JsonGenerator` use to serialize and deserialize regular Java objects (POJOs aka Beans).

### Uses of Versioned in com.fasterxml.jackson.core.base

Classes in com.fasterxml.jackson.core.base that implement Versioned
`class` `GeneratorBase` This base class implements part of API that a JSON generator exposes to applications, adds shared internal methods that sub-classes can use and adds some abstract methods sub-classes must implement.
`class` `ParserBase` Intermediate base class used by all Jackson `JsonParser` implementations.
`class` `ParserMinimalBase` Intermediate base class used by all Jackson `JsonParser` implementations, but does not add any additional fields that depend on particular method of obtaining input.

### Uses of Versioned in com.fasterxml.jackson.core.filter

Classes in com.fasterxml.jackson.core.filter that implement Versioned
`class` `FilteringGeneratorDelegate` Specialized `JsonGeneratorDelegate` that allows use of `TokenFilter` for outputting a subset of content that caller tries to generate.
`class` `FilteringParserDelegate` Specialized `JsonParserDelegate` that allows use of `TokenFilter` for outputting a subset of content that is visible to caller

### Uses of Versioned in com.fasterxml.jackson.core.json

Classes in com.fasterxml.jackson.core.json that implement Versioned
`class` `JsonGeneratorImpl` Intermediate base class shared by JSON-backed generators like `UTF8JsonGenerator` and `WriterBasedJsonGenerator`.
`class` `PackageVersion` Automatically generated from PackageVersion.java.in during packageVersion-generate execution of maven-replacer-plugin in pom.xml.
`class` `ReaderBasedJsonParser` This is a concrete implementation of `JsonParser`, which is based on a `Reader` to handle low-level character conversion tasks.
`class` `UTF8DataInputJsonParser` This is a concrete implementation of `JsonParser`, which is based on a `DataInput` as the input source.
`class` `UTF8JsonGenerator`
`class` `UTF8StreamJsonParser` This is a concrete implementation of `JsonParser`, which is based on a `InputStream` as the input source.
`class` `WriterBasedJsonGenerator` `JsonGenerator` that outputs JSON content using a `Writer` which handles character encoding.

### Uses of Versioned in com.fasterxml.jackson.core.json.async

Classes in com.fasterxml.jackson.core.json.async that implement Versioned
`class` `NonBlockingJsonParser`
`class` `NonBlockingJsonParserBase` Intermediate base class for non-blocking JSON parsers.

### Uses of Versioned in com.fasterxml.jackson.core.util

Classes in com.fasterxml.jackson.core.util that implement Versioned
`class` `JsonGeneratorDelegate`
`class` `JsonParserDelegate` Helper class that implements delegation pattern for `JsonParser`, to allow for simple overridability of basic parsing functionality.
`class` `JsonParserSequence` Helper class that can be used to sequence multiple physical `JsonParser`s to create a single logical sequence of tokens, as a single `JsonParser`.
