org.mmtk.plan.nogc.NoGCCollector
- All Implemented Interfaces:
- Constants
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.
