Interface AsyncVfsEventsListener

All Known Implementing Classes:

GitUntrackedFilesHolder, VcsRootScanner

public interface AsyncVfsEventsListener

Receives notifications about changes in the virtual file system, just as BulkFileListener and VirtualFileListener, but on a pooled thread, which allows to off-load the EDT, but requires more care in the listener code due to asynchrony and the absence of read action. For a safer alternative, consider AsyncFileListener.

Use the AsyncVfsEventsPostProcessor.addListener(AsyncVfsEventsListener, Disposable) to subscribe.

Method Detail

filesChanged

void filesChanged(java.util.List<? extends VFileEvent> events)

Invoked after the given events were applied to the VFS.

The call happens on a pooled thread, under a special ProgressIndicator which is cancelled on project disposal, thus one can call ProgressManager.checkCancelled() to cancel the background task when the project is disposed.
