示例1: if
/*! Notifies all interested listeners of this transaction about the \a event.
If \a event is a closing event (ie. TRANSACTION_ENDED, and
TRANSACTION_ABORTED), all listeners except those listening to
TRANSACTION_WRITTEN will be removed.
*/
static void
notify_transaction_listeners(block_cache* cache, cache_transaction* transaction,
int32_t event)
{
bool isClosing = is_closing_event(event);
bool isWritten = is_written_event(event);
ListenerList::Iterator iterator = transaction->listeners.GetIterator();
while (iterator.HasNext()) {
cache_listener* listener = iterator.Next();
bool remove = (isClosing && !is_written_event(listener->events))
|| (isWritten && is_written_event(listener->events));
if (remove)
iterator.Remove();
if ((listener->events & event) != 0)
add_notification(cache, listener, event, remove);
else if (remove)
delete_notification(listener);
}
// This must work asynchronously in the kernel, but since we're not using
// most transaction events, we can do it here.
flush_pending_notifications(cache);
}示例2:
/*! Removes and deletes all listeners that are still monitoring this
transaction.
*/
static void
remove_transaction_listeners(block_cache* cache, cache_transaction* transaction)
{
ListenerList::Iterator iterator = transaction->listeners.GetIterator();
while (iterator.HasNext()) {
cache_listener* listener = iterator.Next();
iterator.Remove();
delete_notification(listener);
}
}示例3: new
static fssh_status_t
add_transaction_listener(block_cache* cache, cache_transaction* transaction,
int32_t events, fssh_transaction_notification_hook hookFunction, void* data)
{
ListenerList::Iterator iterator = transaction->listeners.GetIterator();
