Class ServerSocketFactory

java.lang.Object
org.glassfish.grizzly.config.ssl.ServerSocketFactory
All Implemented Interfaces:
Cloneable
Direct Known Subclasses:
JSSESocketFactory

public abstract class ServerSocketFactory extends Object implements Cloneable
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 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 two categories of methods. First are methods used to create sockets. Second are methods which set properties used in the production of sockets, such as networking options. There is also an environment specific default server socket factory; frameworks will often use their own customized factory.


It may be desirable to move this interface into the java.net package, so that is not an extension but the preferred interface. Should this be serializable, making it a JavaBean which can be saved along with its networking configuration?

  • Method Details

    • createSocket

      public abstract ServerSocket createSocket(int port) throws IOException, InstantiationException
      Returns a server socket which uses all network interfaces on the host, and is bound to a 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
      Throws:
      IOException - for networking errors
      InstantiationException - for construction errors
    • createSocket

      public abstract ServerSocket createSocket(int port, int backlog) throws IOException, InstantiationException
      Returns a server socket which uses all network interfaces on the host, is bound to a 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.
      Parameters:
      port - the port to listen to
      backlog - how many connections are queued
      Throws:
      IOException - for networking errors
      InstantiationException - for construction errors
    • createSocket

      public abstract ServerSocket createSocket(int port, int backlog, InetAddress ifAddress) throws IOException, InstantiationException
      Returns a server socket which uses only the specified network interface on the local host, is bound to a 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.
      Parameters:
      port - the port to listen to
      backlog - how many connections are queued
      ifAddress - the network interface address to use
      Throws:
      IOException - for networking errors
      InstantiationException - for construction errors
    • acceptSocket

      public abstract Socket acceptSocket(ServerSocket socket) throws IOException
      Wrapper function for accept(). This allows us to trap and translate exceptions if necessary
      Throws:
      IOException
    • handshake

      public abstract void handshake(Socket sock) throws IOException
      Extra function to initiate the handshake. Sometimes necessary for SSL
      Throws:
      IOException
    • init

      public abstract void init() throws IOException
      Throws:
      IOException
    • initSocket

      public void initSocket(Socket s)
    • getSSLContext

      public SSLContext getSSLContext()
      Return the SSLContext required when implementing SSL over NIO non-blocking.
      Returns:
      SSLContext
    • setAttribute

      public void setAttribute(String name, Object value)
      General mechanism to pass attributes from the ServerConnector to the socket factory. Note that the "preferred" mechanism is to use bean setters and explicit methods, but this allows easy configuration via server.xml or simple Properties
    • getDefault

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