John,
Note that in 4.0, the clear method (probably should be "empty" to be
consistent with the other collection classes) would be best
implemented by C code using the RexxClearQueue() API I just added.
The file in question is interpreter/classes/RexxQueueMethods.cpp. The
code would be basically this:
/********************************************************************************************/
/* Rexx_clear_queue
*/
/********************************************************************************************/
RexxMethod0(int, rexx_clear_queue)
{
/* get the queue name */
RexxObjectPtr queue_name = context->GetObjectVariable("NAMED_QUEUE");
/* pull a line
*/
return RexxClearQueue(context->ObjectToStringValue(queue_name));
}
You should be able to add that at the end of the RexxQueueMethods.cpp
file, then in the RexxQueue ooRexx code, you reference that using:
::METHOD empty EXTERNAL 'LIBRARY REXX rexx_clear_queue'
