--------------------------------------------
Summary: Add clone method to GraphTraversal interface
Key: TINKERPOP-2515
URL: https://issues.apache.org/jira/browse/TINKERPOP-2515
Project: TinkerPop
Issue Type: Improvement
Affects Versions: 3.4.9
Reporter: Christopher Smith
The canonical recommendation for reusing traversal parts (e.g., I have a method
that takes a {{GraphTraversal}} as a parameter, and I need to apply {{.id()}}
to it) is to call {{clone()}} on the traversal. However, the interface
{{GraphTraversal}} does not actually provide a {{clone()}} method, and
{{Object#clone()}} is protected. The universal actual implementations
{{DefaultTraversal}} and {{DefaultGraphTraversal}} explicitly expose
{{clone()}}, but they're hidden behind the interfaces.
To provide Java/STC compatibility, {{GraphTraversal}} (and possibly
{{Traversal}}) should expose the {{clone()}} methods.
