Constructor Detail

RMISocketFactory

public RMISocketFactory(java.util.Vector<java.lang.String> aHosts)

Constructor with one parameter.

Parameters:

aHosts - Vector object of provided hosts

Method Detail

createServerSocket

public java.net.ServerSocket createServerSocket(int aPort)
                                         throws java.io.IOException

Create a server socket on the specified port.

Specified by:

createServerSocket in interface java.rmi.server.RMIServerSocketFactory

Parameters:

aPort - the port. port 0 indicates an anonymous port

Returns:

the server socket on the specified port

Throws:

java.io.IOException - if I/O error occurs during server socket creation

createSocket

public java.net.Socket createSocket(java.lang.String host,
                                    int port)
                             throws java.io.IOException

Create a client socket connected to the specified host and port.

Specified by:

createSocket in interface java.rmi.server.RMIClientSocketFactory

Parameters:

host - the host name

port - the port number

Returns:

a socket connected to the specified host and port

Throws:

java.io.IOException - if I/O error occurs during socket creation

setLocalThreadSocket

protected static void setLocalThreadSocket(java.net.Socket aSocket)

Sets the current thread's copy of this thread-local variable to the specified value. Many applications will have no need for this functionality, relying solely on the initialValue method to set the values of thread-locals.

Parameters:

aSocket - the value to be stored in the current threads' copy of this thread-local.

allowConnection

public static boolean allowConnection()
                               throws java.lang.Exception

Verifies access of the socket associated with the current thread to this RMISocketFactory.

Returns:

true if the socket has access, otherwise returns false

Throws:

java.lang.Exception - if no Socket is associated with the current thread
