Package org.elasticsearch.transport.nio

Class ESSelector

java.lang.Object

org.elasticsearch.transport.nio.ESSelector

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

Direct Known Subclasses:

AcceptingSelector, SocketSelector

public abstract class ESSelector
extends java.lang.Object
implements java.io.Closeable

This is a basic selector abstraction used by NioTransport. This selector wraps a raw nio Selector. When you call runLoop(), the selector will run until close() is called. This instance handles closing of channels. Users should call queueChannelClose(NioChannel) to schedule a channel for close by this selector.

Children of this class should implement the specific processKey(SelectionKey), preSelect(), and cleanup() functionality.
