public class RCCollector
extends RCBaseCollector

This class implements the collector context for a reference counting collector. See Shahriyar et al for details of and rationale for the optimizations used here (http://dx.doi.org/10.1145/2258996.2259008). See Chapter 4 of Daniel Frampton's PhD thesis for details of and rationale for the cycle collection strategy used by this collector.
