> Create FocusArchive processor
> -----------------------------
>
> Key: MINIFICPP-39
> URL: https://issues.apache.org/jira/browse/MINIFICPP-39
> Project: NiFi MiNiFi C++
> Issue Type: Task
> Reporter: Andrew Christianson
> Assignee: Andrew Christianson
> Priority: Minor
>
> Create an FocusArchive processor which implements a lens over an archive
> (tar, etc.). A concise, though informal, definition of a lens is as follows:
> "Essentially, they represent the act of “peering into” or “focusing in on”
> some particular piece/path of a complex data object such that you can more
> precisely target particular operations without losing the context or
> structure of the overall data you’re working with."
> https://medium.com/@dtipson/functional-lenses-d1aba9e52254#.hdgsvbraq
> Why an FocusArchive in MiNiFi? Simply put, it will enable us to "focus in on"
> an entry in the archive, perform processing *in-context* of that entry, then
> re-focus on the overall archive. This allows for transformation or other
> processing of an entry in the archive without losing the overall context of
> the archive.
> Initial format support is tar, due to its simplicity and ubiquity.
> Attributes:
> - Path (the path in the archive to focus; "/" to re-focus the overall archive)
