Abstract

The present invention solves both the dangling pointer problem and the garbage collection problem in software systems. Safe object pointers are divided into strong and weak pointers. Strong pointers point to an object unless they are explicitly assigned a new value, set to null, or destroyed. Weak pointers point to an object as long as the object has not been destroyed. If an object is destroyed, the weak pointer effectively becomes null, thus allowing the breaking up of cycles of references in a computer memory.
