Instance Method


Forces the context to process changes to the object graph.


func processPendingChanges()


This method causes changes to registered managed objects to be recorded with the undo manager.

In AppKit-based applications, this method is invoked automatically at least once during the event loop (at the end of the loop)—it may be called more often than that if the framework needs to coalesce your changes before doing something else. You can also invoke it manually to coalesce any pending unprocessed changes.
