---------------------------------------
Summary: Make meta-properties accessible via values(...)-step
Key: TINKERPOP-1924
URL: https://issues.apache.org/jira/browse/TINKERPOP-1924
Project: TinkerPop
Issue Type: Improvement
Components: structure
Affects Versions: 3.3.1
Reporter: Daniel Weber
I'm currently running into a situation where I'd like to access meta-properties
through the values(...)-method. Unfortunately, the signature of values() only
takes strings, so this is not possible:
{code:java}
g.V().values(T.id)
{code}
Of course, there's the trivial workaround:
{code:java}
g.V().id()
{code}
However, I'd like to get values for multiple properties, so the workaround
becomes ugly:
{code:java}
// g.V().union(__.id(), __.values('key'))
{code}
That there would be no overload of 'values' supporting T-accessors is a bit
odd. has(...) has an extra overload for T-accessors, property(...) allows
arbitrary objects to be passed in as key. The valueMap-method allows including
T-accessors in the returned map.
Would it be possible to relax the signature of values(...) to take an arbitraty
list of objects instead of property keys of type string? If the discussion here
turns out in favor of such a relaxation, I could try to implement the change.
