Class ServerSocketFactory

java.lang.Object
javax.net.ServerSocketFactory
Direct Known Subclasses:
SSLServerSocketFactory
public abstract class ServerSocketFactory extends Object
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.

    • ServerSocketFactory

      protected ServerSocketFactory()
      Creates a server socket factory.

  • Method Details

    • getDefault

      public static ServerSocketFactory getDefault()
      Returns a copy of the environment's default socket factory.
      Returns:
      the ServerSocketFactory

    • createServerSocket

      public ServerSocket createServerSocket() throws IOException
      Returns an unbound server socket. The socket is configured with the socket options (such as accept timeout) given to this factory.
      Returns:
      the unbound socket
      Throws:
      IOException - if the socket cannot be created
      See Also:

    • createServerSocket

      public abstract ServerSocket createServerSocket(int port) throws IOException
      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.
      Parameters:
      port - the port to listen to
      Returns:
      the ServerSocket
      Throws:
      IOException - for networking errors
      IllegalArgumentException - if the port parameter is outside the specified range of valid port values, which is between 0 and 65535, inclusive.

    • createServerSocket

      public abstract ServerSocket createServerSocket(int port, int backlog) throws IOException
      Returns a server socket bound to the specified port, and uses the specified connection backlog. 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.

      Parameters:
      port - the port to listen to
      backlog - how many connections are queued
      Returns:
      the ServerSocket
      Throws:
      IOException - for networking errors
      IllegalArgumentException - if the port parameter is outside the specified range of valid port values, which is between 0 and 65535, inclusive.

    • createServerSocket

      public abstract ServerSocket createServerSocket(int port, int backlog, InetAddress ifAddress) throws IOException
      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.

      Parameters:
      port - the port to listen to
      backlog - how many connections are queued
      ifAddress - the network interface address to use
      Returns:
      the ServerSocket
      Throws:
      IOException - for networking errors
      IllegalArgumentException - if the port parameter is outside the specified range of valid port values, which is between 0 and 65535, inclusive.
