Scheduler.ShutdownHandler
There is a way to shutdown the hierarchy of schedulers.
|
Constructor and Description |
---|
Scheduler(ConsoleStream logger,
org.junit.runner.Description description,
Scheduler masterScheduler,
SchedulingStrategy strategy)
Should be used with individual pools on suites, classes and methods, see
ParallelComputerBuilder.useSeparatePools() . |
Scheduler(ConsoleStream logger,
org.junit.runner.Description description,
Scheduler masterScheduler,
SchedulingStrategy strategy,
Balancer balancer)
Can be used by e.g.
|
Scheduler(ConsoleStream logger,
org.junit.runner.Description description,
Scheduler masterScheduler,
SchedulingStrategy strategy,
int concurrency) |
Scheduler(ConsoleStream logger,
org.junit.runner.Description description,
SchedulingStrategy strategy)
Use e.g.
|
Scheduler(ConsoleStream logger,
org.junit.runner.Description description,
SchedulingStrategy strategy,
Balancer balancer)
New instances should be used by schedulers with limited concurrency by balancer
against other groups of schedulers.
|
Scheduler(ConsoleStream logger,
org.junit.runner.Description description,
SchedulingStrategy strategy,
int concurrency)
Should be used if schedulers in parallel children and parent use one instance of bounded thread pool.
