Timer Class

Show Source

Used to schedule tasks for future execution in a background thread. Tasks may be scheduled for one-time execution, or for repeated execution at regular intervals. Unlike the java.util.Timer class, this implementation does not silently cancel tasks if a task encounters an exception.

Public Methods

schedule( Runnable task, long delay ) returns void

Schedules the specified task for execution after the specified delay.

task	task to be scheduled.
delay	delay in milliseconds before task is to be executed.

Show Source

schedule( Runnable task, java.util.Date time ) returns void

Schedules the specified task for execution at the specified time. If the time is in the past, the task is scheduled for immediate execution.

task	task to be scheduled.
time	time at which task is to be executed.

Show Source

scheduleAtFixedRate( Runnable task, java.util.Date firstTime, long period ) returns void

Schedules the specified task for repeated fixed-rate execution, beginning at the specified time. Subsequent executions take place at regular intervals, separated by the specified period.

task	Task to be scheduled.
firstTime	First time at which task is to be executed.
period	Time in milliseconds between successive task executions.

scheduleAtFixedRate( Runnable task, long delay, long period ) returns void

Schedules the specified task for repeated fixed-rate execution, beginning at the specified time. Subsequent executions take place at regular intervals, separated by the specified period.

task	Task to be scheduled.
delay	delay in milliseconds before task is to be executed.
period	Time in milliseconds between successive task executions.

Show Source

cancel( ) returns void

Used to shutdown the current timer task

Show Source

initialized( ) returns boolean

Returns true if the time task has been initialized

Static Methods

setInterval( Callback callback, long interval ) returns Timer

Used to repeatedly call a given function/callback, with a fixed time delay between each call. Example:

    setInterval(()->{
        System.out.println(new java.util.Date());
    }, 1000);

callback
interval	Time in milliseconds between successive calls to the callback.

Show Source

setTimeout( Callback callback, long delay ) returns Timer

Used to call a given function/callback after a delay. Example:

    long startTime = System.currentTimeMillis();
    setTimeout(()->{
        System.out.println(System.currentTimeMillis()-startTime);
    }, 1000);

callback
delay	Delay in milliseconds before the callback is called.
