Overview

This is a multi-module umbrella project for Jackson standard text-format dataformat backends.

Dataformat backends are used to support format alternatives to JSON, using general-purpose Jackson API. Formats included allow access using all 3 API styles (streaming, databinding, tree model).

For Jackson 2.x this is done by sub-classing Jackson core abstractions of:

• All backends sub-class JsonFactory, which is factory for:
  • JsonParser for reading data (decoding data encoding in supported format)
  • JsonGenerator for writing data (encoding data using supported format)
• Some backends sub-class ObjectMapper for additional support for databinding

there will be some changes (such as introduction of format-specific ObjectMapper sub-classes) in Jackson 3.0.

Branches

master branch is for developing the next major Jackson version -- 3.0 -- but there are active maintenance branches in which much of development happens:

• 2.13 is for developing the next minor 2.x version
• 2.12 is for backported fixes for 2.12 patch versions

Older branches are usually not changed but are available for historic reasons. All released versions have matching git tags (jackson-dataformats-text-2.9.4).

Note that since individual format modules used to live in their own repositories, older branches and tags do not exist in this repository.

Textual formats included

Currently included backends are:

• CSV
• Properties
• TOML (since 2.13)
• YAML

Standard supported formats that are not yet included here (but are likely added in future) are:

• XML

<dependency>
  <groupId>com.fasterxml.jackson.dataformat</groupId>
  <artifactId>jackson-dataformat-[FORMAT]</artifactId>
  <version>2.12.2</version>
</dependency>

where [FORMAT] is one of supported modules (csv, properties, toml, yaml)
