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:
JsonParserfor reading data (decoding data encoding in supported format)
JsonGeneratorfor writing data (encoding data using supported format)
- Some backends sub-class
ObjectMapperfor additional support for databinding
there will be some changes (such as introduction of format-specific
sub-classes) in Jackson 3.0.
master branch is for developing the next major Jackson version -- 3.0 -- but there
are active maintenance branches in which much of development happens:
2.14is for developing the next minor 2.x version
2.12are for backported fixes for 2.13/2.12 patch versions (respectively)
Older branches are usually not changed but are available for historic reasons.
All released versions have matching git tags (
Note that since individual format modules used to live in their own repositories, older branches and tags do not exist in this repository.
