class AutoReleasePool
An AutoReleasePool implements simple garbage collection for
reference-counted objects.
It temporarily takes ownwership of reference-counted objects that
nobody else wants to take ownership of and releases them
at a later, appropriate point in time.
Note: The correct way to add an object hold by an AutoPtr<> to
an AutoReleasePool is by invoking the AutoPtr's duplicate()
method. Example:
AutoReleasePool<C> arp;
AutoPtr<C> ptr = new C;
...
arp.add(ptr.duplicate());
{
public:
AutoReleasePool()
Creates the AutoReleasePool.
{
}
~AutoReleasePool()
Destroys the AutoReleasePool and releases
all objects it currently holds.
{
release();
}
void add(C* pObject)
Adds the given object to the AutoReleasePool.
The object's reference count is not modified
{
if (pObject)
_list.push_back(pObject);
}
void release()
Releases all objects the AutoReleasePool currently holds
by calling each object's release() method.
{
while (!_list.empty())
{
_list.front()->release();
_list.pop_front();
}
}
private:
typedef std::list<C*> ObjectList;
ObjectList _list;
