public final class GlobalEventExecutor extends AbstractScheduledEventExecutor
EventExecutor
. It starts the thread automatically and stops it when there is no
task pending in the task queue for 1 second. Please note it is not scalable to schedule large number of tasks to
this executor; use a dedicated executor.Modifier and Type | Field and Description |

EventExecutorGroup
EventExecutorGroup.isShuttingDown()
starts to return true
, and the executor prepares to shut itself down.
Unlike EventExecutorGroup.shutdown()
, graceful shutdown ensures that no tasks are submitted for 'the quiet period'
(usually a couple seconds) before it shuts itself down. If a task is submitted during the quiet period,
it is guaranteed to be accepted and the quiet period will start over.quietPeriod
- the quiet period as described in the documentationtimeout
- the maximum amount of time to wait until the executor is EventExecutorGroup.shutdown()
regardless if a task was submitted during the quiet periodunit
- the unit of quietPeriod
and timeout
