reference counting : FOLDOC
reference counting
A garbage collection technique where each {memory cell} contains a count of the number of other cells which point to it. If this count reaches zero the cell is freed and its pointers to other cells are followed to decrement their counts, and so on {recursively}.
This technique cannot cope with {circular data structures}. Cells in such structures refer (indirectly) to themselves and so will never have a zero reference count. This means they would never be reclaimed, even when there are no references from outside the structure.
