示例1: MessageQueue
int
main(int argc, char **argv)
{
unsigned int id;
MessageQueue *mq = new MessageQueue();
cout << "Message queue initialized, now appending three test messages" << endl;
TestInterface::SetTestIntMessage *m1 = new TestInterface::SetTestIntMessage(1);
TestInterface::SetTestIntMessage *m2 = new TestInterface::SetTestIntMessage(2);
TestInterface::SetTestIntMessage *m3 = new TestInterface::SetTestIntMessage(3);
TestInterface::SetTestStringMessage *m4 = new TestInterface::SetTestStringMessage();
id = mq->append(m1);
cout << "m1 added with id " << id << endl;
id = mq->append(m1);
cout << "m1 added with id " << id << endl;
id = mq->append(m2);
cout << "m2 added with id " << id << endl;
id = mq->append(m3);
cout << "m3 added with id " << id << endl;
id = mq->append(m4);
cout << "m4 (of different type!) added with id " << id << endl;
cout << "Size is now " << mq->size() << endl;
cout << "Unreferencing messages" << endl;
m1->unref();
m2->unref();
m3->unref();
m4->unref();
cout << "Appending m1 again" << endl;
id = mq->append(m1);
cout << "m1 added with id " << id << endl;
cout << "Size is now " << mq->size() << endl;
cout << "m1 refcount is now " << m1->refcount() << endl;
printMessages(mq);
cout << "Now removing message m1 once" << endl;
mq->remove(m1);
printMessages(mq);
cout << "m1 has refcount " << m1->refcount() << endl;
cout << "Now removing message m2" << endl;
mq->remove(m2);
printMessages(mq);
cout << "Now removing message m4" << endl;
mq->remove(m4);
printMessages(mq);
cout << "Size is now " << mq->size() << endl;
printMessages(mq);
delete mq;
// messages will be erased when enqueued in mq!
