ServerSocketFactory

public abstract class ServerSocketFactory
extends Object

java.lang.Object
↳	javax.net.ServerSocketFactory

Known Direct Subclasses

SSLServerSocketFactory

This class creates server sockets. It may be subclassed by other factories, which create particular types of server sockets. This provides a general framework for the addition of public socket-level functionality. It is the server side analogue of a socket factory, and similarly provides a way to capture a variety of policies related to the sockets being constructed.

Like socket factories, server Socket factory instances have methods used to create sockets. There is also an environment specific default server socket factory; frameworks will often use their own customized factory.

Summary

Protected constructors
`ServerSocketFactory()` Creates a server socket factory.

Public methods
`abstract ServerSocket`	`createServerSocket(int port)` Returns a server socket bound to the specified port.
`ServerSocket`	`createServerSocket()` Returns an unbound server socket.
`abstract ServerSocket`	`createServerSocket(int port, int backlog, InetAddress ifAddress)` Returns a server socket bound to the specified port, with a specified listen backlog and local IP.
`abstract ServerSocket`	`createServerSocket(int port, int backlog)` Returns a server socket bound to the specified port, and uses the specified connection backlog.
`static ServerSocketFactory`	`getDefault()` Returns a copy of the environment's default socket factory.

Inherited methods

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

ServerSocketFactory

Added in API level 1

ServerSocketFactory ()

Creates a server socket factory.

Public methods

createServerSocket

Added in API level 1

ServerSocket createServerSocket (int port)

Returns a server socket bound to the specified port. The socket is configured with the socket options (such as accept timeout) given to this factory.

If there is a security manager, its checkListen method is called with the port argument as its argument to ensure the operation is allowed. This could result in a SecurityException.

Parameters
`port`	`int`: the port to listen to

Returns
`ServerSocket`	the `ServerSocket`

Throws
`IOException`	for networking errors
`SecurityException`	if a security manager exists and its `checkListen` method doesn't allow the operation.
`IllegalArgumentException`	if the port parameter is outside the specified range of valid port values, which is between 0 and 65535, inclusive.

createServerSocket

Added in API level 1

ServerSocket createServerSocket ()

Returns an unbound server socket. The socket is configured with the socket options (such as accept timeout) given to this factory.

Returns
`ServerSocket`	the unbound socket

Throws
`IOException`	if the socket cannot be created

createServerSocket

Added in API level 1

ServerSocket createServerSocket (int port, 
                int backlog, 
                InetAddress ifAddress)

Returns a server socket bound to the specified port, with a specified listen backlog and local IP.

The ifAddress argument can be used on a multi-homed host for a ServerSocket that will only accept connect requests to one of its addresses. If ifAddress is null, it will accept connections on all local addresses. The socket is configured with the socket options (such as accept timeout) given to this factory.

The backlog argument must be a positive value greater than 0. If the value passed if equal or less than 0, then the default value will be assumed.

If there is a security manager, its checkListen method is called with the port argument as its argument to ensure the operation is allowed. This could result in a SecurityException.

Parameters
`port`	`int`: the port to listen to
`backlog`	`int`: how many connections are queued
`ifAddress`	`InetAddress`: the network interface address to use

Returns
`ServerSocket`	the `ServerSocket`

Throws
`IOException`	for networking errors
`SecurityException`	if a security manager exists and its `checkListen` method doesn't allow the operation.
`IllegalArgumentException`	if the port parameter is outside the specified range of valid port values, which is between 0 and 65535, inclusive.

The backlog argument must be a positive value greater than 0. If the value passed if equal or less than 0, then the default value will be assumed.

If there is a security manager, its checkListen method is called with the port argument as its argument to ensure the operation is allowed. This could result in a SecurityException.

Parameters
`port`	`int`: the port to listen to
`backlog`	`int`: how many connections are queued

Returns
`ServerSocket`	the `ServerSocket`

Throws
`IOException`	for networking errors
`SecurityException`	if a security manager exists and its `checkListen` method doesn't allow the operation.
`IllegalArgumentException`	if the port parameter is outside the specified range of valid port values, which is between 0 and 65535, inclusive.
