ServerGremlinExecutor (Apache TinkerPop 3.7.2-SNAPSHOT API)

java.lang.Object
- org.apache.tinkerpop.gremlin.server.util.ServerGremlinExecutor

```
public class ServerGremlinExecutor
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. A typical usage would be to instantiate the GremlinServer and then immediately call GremlinServer.getServerGremlinExecutor() which would allow the opportunity to assign "host options" which could be used by a custom Channelizer. Add these options before calling GremlinServer.start() to be sure the Channelizer gets access to those.

Constructor Detail
- ServerGremlinExecutor
```
public ServerGremlinExecutor(Settings settings,
                             ExecutorService gremlinExecutorService,
                             ScheduledExecutorService scheduledExecutorService)
```
  Create a new object from Settings where thread pools are externally assigned. 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.
