This project contains core genera-purpose annotations for Jackson Data Processor, used on value and handler types. Only those annotations that have no dependencies to other core packages are included here: so anything that does depend on ‘jackson-databind’ package are included in that package and so forth.
Project contains versions 2.0 and above: source code for earlier (1.x) versions is available from Codehaus SVN repository. Note that with version 1.x these annotations were part of the ‘core jar’.
