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.

Constructs a new SelectorProvider.
Public Methods
Channel inheritedChannel()
Returns the channel inherited from the process that created this VM.
abstract DatagramChannel openDatagramChannel()
Creates a new open DatagramChannel.
abstract Pipe openPipe()
Creates a new Pipe.
abstract AbstractSelector openSelector()
Creates a new selector.
abstract ServerSocketChannel openServerSocketChannel()
Creates a new open ServerSocketChannel.
abstract SocketChannel openSocketChannel()
Create a new open SocketChannel.
static SelectorProvider provider()
Gets a provider instance by executing the following steps when called for the first time:
  • if the system property "java.nio.channels.spi.SelectorProvider" is set, the value of this property is the class name of the provider returned;
  • if there is a provider-configuration file named "java.nio.channels.spi.SelectorProvider" in META-INF/services of a jar file valid in the system class loader, the first class name is the provider's class name;
  • otherwise, a system default provider will be returned.

Returns
  • the new channel.
Throws
IOException if an I/O error occurs.

public abstract Pipe openPipe ()

Added in API level 1
