expirationHandler

public BGTask.Block_expirationHandler_ret expirationHandler()

Called by the system shortly before your app's background time expires.

There is a limit to how long your app has to perform its background work, and your work may need to be interrupted if system conditions change. Assign a handler to this property to cancel any ongoing tasks, perform any needed cleanup, and then call setTaskCompletedWithSuccess: to signal completion to the system and allow your app to be suspended. This property is cleared after it is called by the system or when setTaskCompletedWithSuccess: is called. This is to mitigate the impact of a retain cycle created by referencing the BGTask instance inside this block.

hash_static

public static long hash_static()

identifier

public java.lang.String identifier()

The identifier associated with the request used to schedule this background work.

init

public BGTask init()

Overrides:

init in class NSObject

instanceMethodForSelector

public static NSObject.Function_instanceMethodForSelector_ret instanceMethodForSelector(org.moe.natj.objc.SEL aSelector)

instanceMethodSignatureForSelector

public static NSMethodSignature instanceMethodSignatureForSelector(org.moe.natj.objc.SEL aSelector)

instancesRespondToSelector

public static boolean instancesRespondToSelector(org.moe.natj.objc.SEL aSelector)

isSubclassOfClass

public static boolean isSubclassOfClass(org.moe.natj.objc.Class aClass)

keyPathsForValuesAffectingValueForKey

public static NSSet<java.lang.String> keyPathsForValuesAffectingValueForKey(java.lang.String key)

new_objc

public static BGTask new_objc()

resolveClassMethod

public static boolean resolveClassMethod(org.moe.natj.objc.SEL sel)

resolveInstanceMethod

public static boolean resolveInstanceMethod(org.moe.natj.objc.SEL sel)

setExpirationHandler

public void setExpirationHandler(BGTask.Block_setExpirationHandler value)

Called by the system shortly before your app's background time expires.

There is a limit to how long your app has to perform its background work, and your work may need to be interrupted if system conditions change. Assign a handler to this property to cancel any ongoing tasks, perform any needed cleanup, and then call setTaskCompletedWithSuccess: to signal completion to the system and allow your app to be suspended. This property is cleared after it is called by the system or when setTaskCompletedWithSuccess: is called. This is to mitigate the impact of a retain cycle created by referencing the BGTask instance inside this block.

setTaskCompletedWithSuccess

public void setTaskCompletedWithSuccess(boolean success)

Marks this task as complete.

Call this method as soon as the background work associated with this task is complete. The system provides your app with a limited amount of time to finish the task. If you do not call setTaskCompletedWithSuccess: on the task, the system continues to run in the background until all the available time is consumed, wasting battery power. The system suspends the app as soon as all background tasks are complete.

Parameters:

success - Whether the task was completed successfully. If the task was unsuccessful, you may request the system to try again later by submitting a new task request to the scheduler before calling this method.

setVersion_static

public static void setVersion_static(long aVersion)

superclass_static

public static org.moe.natj.objc.Class superclass_static()

version_static

public static long version_static()
