Class SwtExec.Guarded

java.lang.Object

com.diffplug.common.rx.GuardedExecutor

com.diffplug.common.swt.SwtExec.Guarded

All Implemented Interfaces:

RxSubscriber, java.util.concurrent.Executor

Enclosing class:

SwtExec

public static class SwtExec.Guarded
extends GuardedExecutor

Executor and Rx for conducting actions which are guarded on an SWT widget. Obtained via SwtExec.guardOn(Widget) or SwtExec.guardOn(ControlWrapper).

 SwtExec.Guarded guarded = SwtExec.immediate().guardOn(textBox);
 // guaranteed to not cause "Widget is disposed" errors
 guarded.subscribe(serverResponse, txt -> textBox.setText(text));

Modifier and Type	Method	Description
java.util.concurrent.ScheduledFuture<?>	schedule(java.lang.Runnable command, long delay, java.util.concurrent.TimeUnit unit)	Same as SwtExec.schedule(Runnable, long, TimeUnit) but automatically cancels when the guard is disposed.
java.util.concurrent.ScheduledFuture<?>	scheduleAtFixedRate(java.lang.Runnable command, long initialDelay, long delay, java.util.concurrent.TimeUnit unit)	Same as SwtExec.scheduleAtFixedRate(Runnable, long, long, TimeUnit) but automatically cancels when the guard is disposed.
java.util.concurrent.ScheduledFuture<?>	scheduleWithFixedDelay(java.lang.Runnable command, long initialDelay, long delay, java.util.concurrent.TimeUnit unit)	Same as SwtExec.scheduleWithFixedDelay(Runnable, long, long, TimeUnit) but automatically cancels when the guard is disposed.
void	timerExec(int delayMs, java.lang.Runnable runnable)	Runs the given runnable after the given delay iff the guard widget is not disposed.

Method Detail

timerExec

public void timerExec(int delayMs,
                      java.lang.Runnable runnable)

Runs the given runnable after the given delay iff the guard widget is not disposed.

schedule

public java.util.concurrent.ScheduledFuture<?> schedule(java.lang.Runnable command,
                                                        long delay,
                                                        java.util.concurrent.TimeUnit unit)

Same as SwtExec.schedule(Runnable, long, TimeUnit) but automatically cancels when the guard is disposed. Identical behavior for `immediate()`, `async()`, etc.

scheduleWithFixedDelay

public java.util.concurrent.ScheduledFuture<?> scheduleWithFixedDelay(java.lang.Runnable command,
                                                                      long initialDelay,
                                                                      long delay,
                                                                      java.util.concurrent.TimeUnit unit)

Same as SwtExec.scheduleWithFixedDelay(Runnable, long, long, TimeUnit) but automatically cancels when the guard is disposed. Identical behavior for `immediate()`, `async()`, etc.

scheduleAtFixedRate

public java.util.concurrent.ScheduledFuture<?> scheduleAtFixedRate(java.lang.Runnable command,
                                                                   long initialDelay,
                                                                   long delay,
