Package org.eclipse.jetty.io

Class ManagedSelector

java.lang.Object

org.eclipse.jetty.util.component.AbstractLifeCycle

org.eclipse.jetty.util.component.ContainerLifeCycle

org.eclipse.jetty.io.ManagedSelector

All Implemented Interfaces:

Container, Destroyable, Dumpable, LifeCycle

public class ManagedSelector
extends ContainerLifeCycle
implements 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.
