| Methods Summary |

| public void | ensureExceptionThrownIfOptionIsUnsupportedOnOS(int option)This method should be called at the end of a socket option test's code
but before the exception catch statements. It throws a failure if the
option given is not supported on the current platform but the VM failed
to throw an exception. So, on platforms which do not support the option,
the execution should never get to this method.
if (!getOptionIsSupported(option)) {
String platform = System.getProperty("os.name");
String version = System.getProperty("os.version");
fail("Failed to throw exception for unsupported socket option: "
+ getSocketOptionString(option));
}
|
| public boolean | getOptionIsSupported(int option)Answer whether the OS supports the given socket option.

| private java.lang.String | getSocketOptionString(int option)Answer a string for the socket option given.

| public void | handleException(java.lang.Exception e, int option)If the exception is "socket does not support the operation" exception and
it is expected on the current platform, do nothing. Otherwise, fail the
test.
