This introduces just the annotation with analysis and validation in
`DoFnSignature`. To keep reviews small and easy (and happening in parallel with
other functionality) my plan is to gradually introduce the annotations and
validation, while rejecting pipelines that actually use them.
You can merge this pull request into a Git repository by running:
$ git pull https://github.com/kennknowles/incubator-beam
DoFn-State-annotations
Alternatively you can review and apply these changes as the patch at:
https://github.com/apache/incubator-beam/pull/1086.patch
To close this pull request, make a commit to your master/trunk branch

Add DoFn.StateId annotation and validation on fields

> Add user-ready API for interacting with state

> Project: Beam
> Issue Type: Sub-task
> Components: sdk-java-core
> Reporter: Kenneth Knowles
> Assignee: Kenneth Knowles
> Labels: State
>
> Our current state API is targeted at runner implementers, not pipeline
> authors. As such it has many capabilities that are not necessary nor
> desirable for simple use cases of stateful ParDo (such as dynamic state tag
> creation). Implement a simple state intended for user access.
> (Details of our current thoughts in forthcoming design doc)
