What is Ensweep in Computer Programming?

Ensweep is a term used in the context of garbage collection in computer programming. It refers to the process of sweeping the heap (a data structure used to store dynamic memory allocation) for objects that are no longer reachable, and therefore can be safely collected.

In other words, ensweep is the process of finding all the objects in the heap that have no references pointing to them, and marking them as garbage so that they can be reclaimed by the garbage collector. This helps to free up memory that is no longer being used, which can improve the performance of the program by reducing the amount of memory that needs to be allocated and deallocated.

Ensweep is typically done in conjunction with a garbage collection cycle, where the heap is scanned for garbage objects and any unreachable objects are marked for collection. The process of ensweep is often referred to as "sweeping" or "mark-and-sweep" garbage collection.
