Class IsolatedRegion

java.lang.Object
  orc.runtime.regions.Region
      orc.runtime.regions.IsolatedRegion

public final class IsolatedRegion
extends Region

An isolated region. This does two things: first, it prevents any parent region from linking to tokens in this region, so they may be garbage collected. Second, it records liveness and quiescence in the root region as well as the parent, so the root can't terminate until we do. See Isolate.
