Method Detail

runWithNotificationsSuppressed

public static <T> T runWithNotificationsSuppressed(Computable<T> runnable)

onLowMemorySignalReceived

public static void onLowMemorySignalReceived(boolean afterGc)

register

public static LowMemoryWatcher register(java.lang.Runnable runnable,
                                        LowMemoryWatcher.LowMemoryWatcherType notificationType)

Registers a runnable to run on low memory events

Parameters:

runnable - the action which executes on low-memory condition. Can be executed: - in arbitrary thread - in unpredictable time - multiple copies in parallel so please make it reentrant.

notificationType - When ONLY_AFTER_GC, then the runnable will be invoked only if the low-memory condition still exists after GC. When ALWAYS, then the runnable also will be invoked when the low-memory condition is detected before GC.

Returns:

a LowMemoryWatcher instance holding the runnable. This instance should be kept in memory while the low memory notification functionality is needed. As soon as it's garbage-collected, the runnable won't receive any further notifications.

register

public static LowMemoryWatcher register(java.lang.Runnable runnable)

register

public static void register(java.lang.Runnable runnable,
                            LowMemoryWatcher.LowMemoryWatcherType notificationType,
                            Disposable parentDisposable)

Registers a runnable to run on low memory events. The notifications will be issued until parentDisposable is disposed.

register

public static void register(java.lang.Runnable runnable,
                            Disposable parentDisposable)
