Interface SocketFactory

Known Implementing Classes:
DefaultSocketFactory

public interface SocketFactory

This class produces sockets for serving and submitting CORBA requests. The socket factory can be set using gnuOrb.setSocketFactory() for producting all sockets for that ORB. This is needed for using secure sockets, for implementing the desired timeout policies, for HTTP tunnels and in some other similar cases. While such functionality is provided by near all existing CORBA implementations, no standard mechanism is defined. The socket factory may need to put additional information to the IORs of the objects, released by the ORB. Because of this reason, this interface extends IORInterceptorOperations.

Field Summary

static String
PROPERTY
The name of the ORB property that forces the ORB to use the socket factory class, the name of that (String) is the value of this property.

Method Summary

Socket
createClientSocket(String host, int port)
Create a client socket that should send a request to the remote side.
ServerSocket
createServerSocket(int port)
Create a server socket that should serve remote invocations on the given port.

Field Details

PROPERTY

public static final String PROPERTY
The name of the ORB property that forces the ORB to use the socket factory class, the name of that (String) is the value of this property.
Field Value:
"gnu.CORBA.SocketFactory"

Method Details

createClientSocket

public Socket createClientSocket(String host,
                                 int port)
            throws IOException
Create a client socket that should send a request to the remote side. When returned, the socket should be opened and ready to communicate.
Parameters:
port - the port, on that the socket should be openend. The port is usually part of the internet profile.
Throws:
IOException - if the socket cannot be created on the given port due any reasons. The ORB may try to open the socket on another port, calling this method with the different parameter.

createServerSocket

public ServerSocket createServerSocket(int port)
            throws IOException
Create a server socket that should serve remote invocations on the given port. The ORB may use this socket to serve either one or more objects.
Parameters:
port - the port, on that the socket should be listening for requests. The port policy can be controlled by gnuPortManager.
Throws:
IOException - if the socket cannot be created on the given port due any reasons. The ORB may try to open the socket on another port, calling this method with the different parameter.
