org.mmtk.plan.nogc.NoGCCollector

public class NoGCCollector
extends ParallelCollector

This class implements per-collector thread behavior and state for the NoGC plan, which simply allocates (without ever collecting until the available space is exhausted.

Specifically, this class would define NoGC collection time semantics, however, since this plan never collects, this class consists only of stubs which may be useful as a template for implementing a basic collector.
