A pool that keeps track of objects to release.
The OFAutoreleasePool class is a class that keeps track of objects that will be released when the autorelease pool is released.
Every thread has its own stack of autorelease pools.
+ (void) addObject: | (id) | object |
Adds an object to the autorelease pool at the top of the thread-specific autorelease pool stack.
object | The object to add to the autorelease pool |
- (void) releaseObjects |
Releases all objects in the autorelease pool.
This does not free the memory allocated to store pointers to the objects in the pool, so reusing the pool does not allocate any memory until the previous number of objects is exceeded. It behaves this way to optimize loops that always work with the same or similar number of objects and call relaseObjects at the end of the loop, which is propably the most common case for releaseObjects.
If a garbage collector is added in the future, it will tell the GC that now is a good time to clean up, as this is often used after a lot of objects have been added to the pool that should be released before the next iteration of a loop, which adds objects again. Thus, it is usually a clean up call.
