Class ManagedSelector

  • All Implemented Interfaces:
    org.eclipse.jetty.util.component.Container, org.eclipse.jetty.util.component.Destroyable, org.eclipse.jetty.util.component.Dumpable, org.eclipse.jetty.util.component.LifeCycle
    public class ManagedSelector
extends org.eclipse.jetty.util.component.ContainerLifeCycle
implements org.eclipse.jetty.util.component.Dumpable

    ManagedSelector wraps a Selector simplifying non-blocking operations on channels.

    ManagedSelector runs the select loop, which waits on Selector.select() until events happen for registered channels. When events happen, it notifies the EndPoint associated with the channel.
