Java Forum / General / November 2005ServerSocket.accept() & Socket subclass
hello ! - Why doing that is incorrect ? --- code --- ServerSocket serverSocket = new ServerSocket(11000); MySocket socket = serverSocket.accept(); --- /code --- where MySocket is a subclass of java.net.Socket. - Is there a mean to achieve this without using an encapsulation like MySocket mySocket = new MySocket(java.net.Socket socket) ? Thanks. -o-- "oziris" <oziris.groups@gmail.com> wrote in news:1132735967.644492.234110 @z14g2000cwz.googlegroups.com: > hello ! > [quoted text clipped - 6 lines] > > where MySocket is a subclass of java.net.Socket. That looks fine to me. Why do you think it is incorrect? > - Is there a mean to achieve this without using an encapsulation like > > MySocket mySocket = new MySocket(java.net.Socket socket) ? > > Thanks. What are you trying to do here? Some more information (and code) would be nice. I had to write a specific Socket class. So now I would ServerSocket.accept() returns an instance of this class. The instruction MySocket socket = (MySocket)serverSocket.accept(); throws a ClassCastException. According to a reply to the same message on fr.comp.lang.java, the means seems to consist in extend SocketImpl and related classes. -o-- > I had to write a specific Socket class.

Have you looked at ServerSocket.setSocketFactory()? /gordon  Signature[ do not email me copies of your followups ] g o r d o n + n e w s @ b a l d e r 1 3 . s e Here the reply of Fabien Bergeret on fr.comp.lang.java Alors, faut creer une classe MySocket heritant de SocketImpl, puis creer une classe MySocketImplFactory qui implemente SocketImplFactory, et enfin appeler la methode statique setSocketImplFactory de la classe Socket. C'est tout ! :-) In English You must create a class MySocket which extends SocketImpl and then a class MySocketImplFactory which implements SocketImplFactory. And finally you have to call the static method Socket.setSocketImplFactory. That's all :-) Subject closed.

[quoted text clipped - 9 lines] > > -o-- That's not the same code as what you gave in the original post :-) This of course fails because serverSocket.accept() returns a Socket, not MySocket. MySocket is a Socket, but not the other way around. The SocketFactory method mentioned in the other post could work, or you can do what you originally said: MySocket socket = new MySocket(serverSocket.accept()); The SocketFactory way is cleaner, but more typing.
