---------------------------------------------
Summary: Lambda based {{withStrategies()}} and String-based
{{withoutStrategies()}}.
Key: TINKERPOP-1455
URL: https://issues.apache.org/jira/browse/TINKERPOP-1455
Project: TinkerPop
Issue Type: Improvement
Components: language-variant, process
Affects Versions: 3.2.2
Reporter: Marko A. Rodriguez
Right now {{withStrategies()}} is not supported by Gremlin-Python. Why? Because
strategies are created via Java and thus you can't do stuff like:
{code}
g.withStrategies(SubgraphStrategy.build()...create())
{code}
Now, we have strategies that we have made "native" to {{GraphTraversalSource}}
by way of {{withXXX}}. For example: {{withSideEffect()}}, {{withSack()}},
{{withRemote()}}, {{withPath()}}, etc.
In order to generally support any strategy created by a user for use from a
language variant, we should support lambda based strategies. E.g.:
{code}
g.withStrategies(lambda : "SubgraphStrategy.build()...create()")
{code}
Like any other lambda, it is executed server side using the respective
{{ScriptEngine}}.
Next, {{withoutStrategies()}} should support {{String...}} so you can do:
{code}
g.withoutStrategies("com.stuff.MyStrategy", "com.stuff.MyOtherStrategy")
{code}
..instead of having to pass in the {{Class}} object.
