Class StopTheWorldMutator

java.lang.Object
  org.mmtk.plan.MutatorContext
      org.mmtk.plan.SimpleMutator
          org.mmtk.plan.StopTheWorldMutator

All Implemented Interfaces:: Constants

Direct Known Subclasses:: CopyMSMutator, GenMutator, ImmixMutator, MCMutator, MSMutator, RCBaseMutator, SSMutator

public abstract class StopTheWorldMutator
extends SimpleMutator
extends SimpleMutator

This class (and its sub-classes) implement per-mutator thread behavior and state. MMTk assumes that the VM instantiates instances of MutatorContext in thread local storage (TLS) for each application thread. Accesses to this state are therefore assumed to be low-cost during mutator time.
