ACE提供了一种安全的包装类型ACE_Array<T>,能够在访问数组时进行检查,而且还提供了一些有用的特性,比如:复制和比较的语意;

例子代码:

int TestContainers::testACEArray(void)
{
 ACE_DEBUG( (LM_INFO, ACE_TEXT("----------> use ACE_Array <----------\n")) );
 int i = 0;
 DataElement* elem = NULL;
 DataElement** elem2 = NULL;
 ACE_Array<DataElement*> arr(10);
 for(i = 0; i < 10; i++)
 {
  elem = NULL;
  ACE_NEW_RETURN(elem, DataElement(i), -1);
  arr[i] = elem;
 }

 //Check the access
 ACE_ASSERT(arr.set(elem, 11));
 ACE_ASSERT(arr.get(elem, 11));

 //Make a copy
 ACE_Array<DataElement*> copy_arr = arr;
 ACE_ASSERT(copy_arr == arr);

 ACE_DEBUG( (LM_INFO, ACE_TEXT("----> outout with by array index ...\n")) );
 for(i = 0; i < 10; i++)
 {
  ACE_DEBUG( (LM_INFO, ACE_TEXT(" %d"), arr[i]->getData()) );
 }
 ACE_DEBUG( (LM_INFO, ACE_TEXT("\n")) );

 ACE_DEBUG( (LM_INFO, ACE_TEXT("----> outout with ITERATOR ...\n")) );
 ACE_Array<DataElement*>::ITERATOR it(copy_arr);
 while(!(it.done()))
 {
  elem2 = NULL;
  elem = NULL;
  it.next(elem2);
  elem = *elem2;
  if(elem)
  {
   ACE_DEBUG( (LM_INFO, ACE_TEXT("  %d\n"),elem->getData()) );
   delete elem;
  }
  it.advance();
 }
 return 0;
}
