This package contains Jackson extension component for reading and writing XML encoded data.

Further, the goal is to emulate how JAXB data-binding works with "Code-first" approach (that is, no support is added for "Schema-first" approach). Support for JAXB annotations is provided by JAXB annotation module; this module provides low-level abstractions (JsonParser, JsonGenerator, JsonFactory) as well as small number of higher level overrides needed to make data-binding work.

Dataformat backends are used to support format alternatives to JSON, supported by default. This is done by sub-classing Jackson core abstractions.

This package provides the Java development kit OpenJDK.

ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files. It's widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build and walk parse trees.
