spmallette opened a new pull request, #3570:
URL: https://github.com/apache/tinkerpop/pull/3570
The reference documentation for the values()-step listed three examples
against the TinkerPop Crew graph but rendered no output and offered only a
single sentence of prose, so the behavior of the step was difficult to predict
from the docs alone.
This adds:
- An introductory paragraph explaining that values() returns the values of
the requested properties, or of every property when called with no arguments,
and noting that a property may be multi-valued or carry meta-properties.
- Numbered callouts on the three examples clarifying that a no-argument
values() returns every property value across all keys, that the sample vertex
has a multi-valued location property, and that properties('location').values()
extracts meta-property values (the startTime and endTime years) rather than the
city-name values returned by values('location').
- A note that the order in which property values are returned is not
guaranteed.
The examples remain executable, so their output is rendered at build time
rather than hand-written. No behavior changes; this is a documentation-only
improvement.
