                           boolean timeouts)
                    throws IOException

Open the connection

Specified by:

openPrim in interface ConnectionBaseInterface

Parameters:

name - the target for the connection. It must be in this format: "//:"

mode - read/write mode of the connection (currently ignored).

timeouts - A flag to indicate that the called wants timeout exceptions (currently ignored).

Throws:

IOException

open

public void open(int handle,
                 int mode)
