ByCallerThreadGroupPolicy

public ByCallerThreadGroupPolicy(Set<ThreadGroup> waitGroups,
                                 Set<ThreadGroup> runCpuLightWhenTargetBusyGroups,
                                 ThreadGroup couLightGroup,
                                 ThreadGroup parentGroup,
                                 String schedulerName)

Builds a new ByCallerThreadGroupPolicy with the given waitGroups.

Parameters:

waitGroups - the group of threads for which a WaitPolicy will be applied. For the rest, an ThreadPoolExecutor.AbortPolicy (or ThreadPoolExecutor.CallerRunsPolicy if allowed) will be applied.

runCpuLightWhenTargetBusyGroups - the group of threads for which a ThreadPoolExecutor.CallerRunsPolicy will be applied when dispatching to cpu-light.

couLightGroup - the group of cpuLight threads

parentGroup - the SchedulerService parent ThreadGroup

schedulerName - the name of the target Scheduler
