## Class WebSocketClientFactory

- java.lang.Object
- - org.eclipse.jetty.util.component.AbstractLifeCycle
  - - org.eclipse.jetty.util.component.AggregateLifeCycle
    - - org.eclipse.jetty.websocket.WebSocketClientFactory

- All Implemented Interfaces:
    Destroyable, Dumpable, LifeCycle

      public class WebSocketClientFactory
      extends AggregateLifeCycle

  WebSocketClientFactory contains the common components needed by multiple `WebSocketClient` instances (for example, a `ThreadPool`, a `NIO selector`, etc).

  WebSocketClients with different configurations should share the same factory to avoid to waste resources.

  If a ThreadPool or MaskGen is passed in the constructor, then it is not added with `AggregateLifeCycle.addBean(Object)`, so it's lifecycle must be controlled externally.
