This is a multi-module umbrella project for Jackson standard binary 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:
JsonFactory
, which is factory for:
JsonParser
for reading data (decoding data encoding in supported format)JsonGenerator
for writing data (encoding data using supported format)ObjectMapper
(like CBORMapper
, SmileMapper
) for all formats, mostly for convenienceCurrently included backends are:
All modules are licensed under Apache License 2.0.
To use these format backends Maven-based projects, use following dependency:
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-[FORMAT]</artifactId>
<version>2.13.0</version>
</dependency>
where [FORMAT]
is one of supported modules (avro
, cbor
, smile
etc)
You may at-reference them as necessary but please keep in mind that all maintenance work is strictly voluntary (no one gets paid to work on this or any other Jackson components) so there is no guarantee for timeliness of responses.
master
branch is for developing the next major Jackson version -- 3.0 -- but there
are active maintenance branches in which much of development happens:
2.14
is for developing the next 2.x version2.13
and 2.12
are for backported fixes for 2.13/2.12 versions (respectively)Older branches are usually not changed but are available for historic reasons.
All released versions have matching git tags (jackson-dataformats-binary-2.10.3
).
Note that since individual format modules used to live in their own repositories, older branches (before 2.8) and tags do not exist in this repository.
In addition to binary format backends hosted by FasterXML in this repo, there are other known Jackson backends for binary data formats. For example:
MsgPack
