SelectorProvider

extends Object

   ↳ java.nio.channels.spi.SelectorProvider

Class Overview

SelectorProvider is an abstract base class that declares methods for providing instances of DatagramChannel , Pipe , Selector , ServerSocketChannel , and SocketChannel . All the methods of this class are thread-safe.

A provider instance can be retrieved through a system property or the configuration file in a jar file; if no provider is available that way then the system default provider is returned.
