Method Detail

addPlugins

public GremlinExecutor.Builder addPlugins(String engineName,
                                          Map<String,Map<String,Object>> plugins)

Add a configuration for a GremlinPlugin to the executor. The key is the fully qualified class name of the GremlinPlugin instance and the value is a map of configuration values. In that map, the key is the name of a builder method on the GremlinPlugin and the value is some argument to pass to that method.

globalBindings

public GremlinExecutor.Builder globalBindings(Bindings bindings)

Bindings to apply to every script evaluated. Note that the entries of the supplied Bindings object will be copied into a newly created ConcurrentBindings object at the call of this method.

evaluationTimeout

public GremlinExecutor.Builder evaluationTimeout(long evaluationTimeout)

Amount of time an evaluation has before it times out. Note that the time required covers both evaluation as well as any time needed for a post result transformation (if the transformation function is supplied to the GremlinExecutor.eval(java.lang.String)).

Parameters:

evaluationTimeout - Time in milliseconds that an evaluation is allowed to run and its results potentially transformed. Set to zero to have no timeout set.

executorService

public GremlinExecutor.Builder executorService(ExecutorService executorService)

The thread pool used to evaluate scripts.

scheduledExecutorService

public GremlinExecutor.Builder scheduledExecutorService(ScheduledExecutorService scheduledExecutorService)

The thread pool used to schedule timeouts on scripts.

beforeEval

public GremlinExecutor.Builder beforeEval(Consumer<Bindings> beforeEval)

A Consumer to execute just before the script evaluation.

afterSuccess

public GremlinExecutor.Builder afterSuccess(Consumer<Bindings> afterSuccess)

A Consumer to execute just after successful script evaluation. Note that success will be called after evaluation of the script in the engine and after the results have passed through transformation (if a transform function is passed to the GremlinExecutor.eval(java.lang.String).

afterTimeout

public GremlinExecutor.Builder afterTimeout(Consumer<Bindings> afterTimeout)

A Consumer to execute if the script times out.

afterFailure

public GremlinExecutor.Builder afterFailure(BiConsumer<Bindings,Throwable> afterFailure)

A Consumer to execute in the event of failure.

create

public GremlinExecutor create()
