Layout objects use invalidation contexts to optimize the layout process and avoid unnecessary work. You use this class to specify whether the NSCollectionViewFlowLayout object should fetch new size information from its delegate. You can also prevent the flow layout object from updating its layout information altogether.
When you want to invalidate your flow layout object, call the NewInvalidationContext method of your layout object and instantiate the resulting class. (The implementation of that method in NSCollectionViewFlowLayout returns this class.) After instantiating this class, set the properties to appropriate values and pass the object to the invalidateLayoutWithContext method of the layout object.
