| - (void) addObjectForReading: | (id <OFReadyForReadingObserving>) | object |
Adds an object to observe for reading.
This is also used to observe a listening socket for incoming connections, which then triggers a read event for the observed object.
If there is an observe call blocking, it will be canceled. The reason for this is to prevent blocking even though the newly added object is ready.
| object | The object to observe for reading |
| - (void) addObjectForWriting: | (id <OFReadyForWritingObserving>) | object |
Adds an object to observe for writing.
If there is an observe call blocking, it will be canceled. The reason for this is to prevent blocking even though the newly added object is ready.
| object | The object to observe for writing |
| - (void) cancel |
Cancels the currently blocking observe call.
This is automatically done when a new object is added or removed by another thread, but in some circumstances, it might be desirable for a thread to manually stop the observe running in another thread.
| - (id< OFKernelEventObserverDelegate >) delegate |
Returns the delegate for the OFKernelEventObserver.
| - (void) observeForTimeInterval: | (of_time_interval_t) | timeInterval |
Observes all objects until an event happens on an object or the timeout is reached.
| timeInterval | The time to wait for an event, in seconds |
| + (instancetype) observer |
Creates a new OFKernelEventObserver.
| - (void) observeUntilDate: | (OFDate*) | date |
Observes all objects until an event happens on an object or the specified date is reached.
| date | The until which to observe |
| - (void) removeObjectForReading: | (id <OFReadyForReadingObserving>) | object |
Removes an object to observe for reading.
If there is an observe call blocking, it will be canceled. The reason for this is to prevent the removed object from still being observed.
| object | The object to remove from observing for reading |
| - (void) removeObjectForWriting: | (id <OFReadyForWritingObserving>) | object |
Removes an object to observe for writing.
If there is an observe call blocking, it will be canceled. The reason for this is to prevent the removed object from still being observed.
| object | The object to remove from observing for writing |
| - (void) setDelegate: | (nullable id< OFKernelEventObserverDelegate >) | delegate |
Sets the delegate for the OFKernelEventObserver.
| delegate | The delegate for the OFKernelEventObserver |
