When the NSOperation finishes, it will call setNeedsDisplay on the view in the main thread so the view knows to draw the image data to screen. You can do this in real time. Drawing from a buffer is fast. Any time the BigViewPageView is asked to drawRect, it pulls the image data from the current cgContext for drawing; it s also filling new cgContexts in the background if you change the expected drawing size of the image through some bizarre action like zooming. Before the new buffer is ready, your image will stretch to fill and probably pixelate for a moment while the NSOperation is preparing new data.

At this point we have the classical physics of the string in place. The next step toward a quantum theory is, of course, to quantize the string. We will start off by looking at a quantum theory of a single string. From quantum eld theory you recall that this procedure is known as rst quantization. This is opposed to the procedure called second quantization, which is a viewpoint of quantizing elds (see Quantum Field Theory Demysti ed for a review). The difference in the two approaches will be on how we view the Xm(s, t ). If we take them to be elds, then the quantization procedure is second quantization. If we take them to be space-time coordinates, as we have so far, then the process is rst quantization. This is the procedure we will apply in this chapter. There are several different approaches to quantization of the string, each with their own accompanying dif culties and problems. The main approaches used are called covariant quantization, light-cone quantization, and BRST quantization. We consider the rst two approaches here, and will discuss BRST quantization later.

The sample code in Examples/08BigViewThingOperationQueueRegular has all the additional code. It also prints the contents of the NSOperationQueue on a timer to show you what is in there. Build and run in the simulator. The application should remain responsive. Or is it Every time I zoom in or zoom out on an image, the view pushes another NSOperation onto the queue. If you watch the log messages printing the contents of the NSOperationQueue, you will see that there are an ever-growing number of operations for each view getting pushed when there is a lot of zooming going on. This makes the app seem like it s updating less and less often. The queue eventually clears but not after drawing a given image several times, usually at zoom levels not currently needed for drawing. Wouldn t it be nice to be able to cancel only certain pending operations on the NSOperationQueue You can. You just call the cancel method on your NSOperation object; the queue will eventually (but not immediately) remove it, but it will never actually run it. You can add a weak reference to the NSOperation subclass to point back to the BigViewPageView object that placed it on the queue and then ask each NSOperation that belongs to you to cancel before you add another operation to the queue. This way, you can be sure that there is little wasted CPU time.

The procedure known as covariant quantization will be familiar to you from your studies of ordinary quantum mechanics. In a nutshell, this is the imposition of commutation relations on position and momentum. So, using this procedure we continue with the notion that X ( , ) are space-time coordinates, but we need to say what we are taking as the momentum. This can be done in the standard way using lagrangian dynamics. Let ( , ) be the momentum carried by the string. Given a lagrangian density L we can calculate the momentum from the X ( , ) using

NOTE: In this implementation, an operation in progress cannot be canceled, so it s still possible that the queue will have to run two operations for a given view in fairly rapid succession. Once you have that weak reference, it s easy to create a category on NSOperationQueue to cancel all pending NSOperations in the queue filtered by an NSPredicate.

There are several different versions of MPEG compression. They are described in the following sections.

This is easy to calculate using the Polyakov action as written in Eq. (2.31): T d 2 X X X X 2 T L = X X X X 2 SP =

MPEG-1

- (void)cancelOperationsFilteredByPredicate:(NSPredicate *)predicate; { NSArray *ops = [[self operations] filteredArrayUsingPredicate:predicate]; for (NSOperation *op in ops) { if(![op isExecuting] && ![op isFinished] && ![op isCancelled]) { [op cancel]; } } }
