Hello,
I implemented this in the branch TINKERPOP3-798.
https://github.com/apache/incubator-tinkerpop/commit/16d6078ca810e70cb3f62d98fcbbc244819f5bae
Notes:
* mapKeys() <=> select(keys).unfold()
* mapValues() <=> select(values).unfold()
* GraphTraversal.mapXXX() is Deprecated.
* MapKeysStep and MapValuesStep were deleted.
* SelectColumnStep was added.
* SelectColumnStep.Column.keys and SelectColumnStep.Column.values are
new enums that are statically imported.
We could easily add by()-modulation here where, for each key (or value), the
by() traversal processes them. This can always be added later without effecting
backwards compatibility.
Please review the branch and tell me what you think.
Thank you,
Marko.
