public abstract class

SelectorProvider

extends Object

java.lang.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.

Summary

Protected Constructors
	SelectorProvider() 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`.
synchronized 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.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Protected Constructors

protected SelectorProvider ()

Added in API level 1

Constructs a new SelectorProvider.

Public Methods

public Channel inheritedChannel ()

Added in API level 1

Returns the channel inherited from the process that created this VM. On Android, this method always returns null because stdin and stdout are never connected to a socket.

Returns

the channel.

Throws

IOException	if an I/O error occurs.

public abstract DatagramChannel openDatagramChannel ()

Added in API level 1

Creates a new open DatagramChannel.

Returns

the new channel.

Throws

IOException	if an I/O error occurs.

public abstract Pipe openPipe ()

Added in API level 1

Creates a new Pipe.

Returns

the new pipe.

Throws

IOException	if an I/O error occurs.

public abstract AbstractSelector openSelector ()

Added in API level 1

Creates a new selector.

Returns

the new selector.

Throws

IOException	if an I/O error occurs.

public abstract ServerSocketChannel openServerSocketChannel ()

Added in API level 1

Creates a new open ServerSocketChannel.

Returns

the new channel.

Throws

IOException	if an I/O error occurs.

public abstract SocketChannel openSocketChannel ()

Added in API level 1

Create a new open SocketChannel.

Returns

the new channel.

Throws

IOException	if an I/O error occurs.

public static synchronized SelectorProvider provider ()

Added in API level 1

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 provider.
