Attributes

Remarks

Enable/disable the option specified by optID. If the option is to be enabled, and it takes an option-specific "value", this is passed in value. The actual type of value is option-specific, and it is an error to pass something that isn't of the expected type: <BR>

SocketImpl s;
            ...
            s.setOption(SO_LINGER, new Integer(10));
               // OK - set SO_LINGER w/ timeout of 10 sec.
            s.setOption(SO_LINGER, new Double(10));
               // ERROR - expects java.lang.Integer

If the requested option is binary, it can be set using this method by a java.lang.Boolean: <BR>

s.setOption(TCP_NODELAY, Boolean.TRUE);
               // OK - enables TCP_NODELAY, a binary option

<BR> Any option can be disabled using this method with a Boolean.FALSE: <BR>

s.setOption(TCP_NODELAY, Boolean.FALSE);
               // OK - disables TCP_NODELAY
            s.setOption(SO_LINGER, Boolean.FALSE);
               // OK - disables SO_LINGER

<BR> For an option that has a notion of on and off, and requires a non-boolean parameter, setting its value to anything other than Boolean.FALSE implicitly enables it. <BR> Throws SocketException if the option is unrecognized, the socket is closed, or some low-level error occurred <BR>
