Qdeleteall () function deletes all the pointers stored in the container. This function is only applicable if the container element is a pointer. After executing this function, the pointer in the container is executed by the delete operation, but these pointers are still stored in the container and become wild pointers, you need to call the container's clear () function to avoid the misuse of these pointers:Qdeleteall (list);List.clear ();the Qswap () function can exchange the position of two el

predictable. However, the reference relationship may have changed between two sections of the GC program. Therefore, this GC algorithm also writes the barrier to record the change of the reference relationship. Although this method controls the maximum interrupt time, the total GC time is increased due to the increased number of interrupts.With regard to incremental garbage collection, http://blog.csdn.NET/u011320646/article/details/38640703 this blog post is more vivid and needs to be read by
