Class ServerGremlinExecutor<T extends ScheduledExecutorService>

java.lang.Object

org.apache.tinkerpop.gremlin.server.util.ServerGremlinExecutor<T>

public class ServerGremlinExecutor<T extends ScheduledExecutorService>
extends Object

The core of script execution in Gremlin Server. Given Settings and optionally other arguments, this class will construct a GremlinExecutor to be used by Gremlin Server. Those expecting to build their own version of Gremlin Server might consider coring their implementation with this class as it provides some basic infrastructure required for most of Gremlin Server script processing features. Those embedding Gremlin Server in another application might consider using this class to initialize the GremlinServer class as it will allow sharing of thread pool resources.

Constructor Detail

ServerGremlinExecutor

public ServerGremlinExecutor(Settings settings,
                             Class<T> scheduleExecutorServiceClass)

Create a new object from Settings where thread pools are internally created. Note that the scheduleExecutorServiceClass will be created via Executors.newScheduledThreadPool(int, ThreadFactory).

ServerGremlinExecutor

public ServerGremlinExecutor(Settings settings,
                             ExecutorService gremlinExecutorService,
                             T scheduledExecutorService,
                             Class<T> scheduleExecutorServiceClass)

Create a new object from Settings where thread pools are internally created. Note that if the scheduleExecutorServiceClass is set to null it will be created via Executors.newScheduledThreadPool(int, ThreadFactory). If either of the ExecutorService instances are supplied, the Settings.gremlinPool value will be ignored for the pool size.
