Method Details

run

protected void run()

Description copied from class: SingleThreadEventExecutor

Runs the task-processing loop until SingleThreadEventExecutor.confirmShutdown() returns true.

Implementations must not let a Throwable thrown by a task escape this method: any uncaught Throwable terminates the executor (logged at WARN and surfaced via SingleThreadEventExecutor.terminationFuture()), at which point every Channel registered with this executor stops processing I/O and new task submissions are rejected. The supplied helpers - SingleThreadEventExecutor.runAllTasks(), SingleThreadEventExecutor.runAllTasks(long), and AbstractEventExecutor.safeExecute(Runnable) - catch Throwable for you; custom loops built on SingleThreadEventExecutor.pollTask() or SingleThreadEventExecutor.takeTask() are responsible for wrapping each task invocation accordingly.
