implementation

What is the precise implementation of Enumerable.Range in .Net; preferable .Net 4? Is it a yielded for-loop? A custom implementation (IEnumerable, IEnumerator) or? CraigTP The accepted answer on this question should give you the answer: public static class Enumerable { public static IEnumerable<int> Range(int start, int count) { var end = start + count; for(var current = start; current < end; ++current) { yield return current; } } } This isn't the exact code, as there is a lot of error checking etc. going on within the Range method, and internally, it calls other methods, however, the quoted

As a C++ programmer becoming more familiar with Java, it's a little odd to me to see language level support for locking on arbitrary objects without any kind of declaration that the object supports such locking. Creating mutexes for every object seems like a heavy cost to be automatically opted into. Besides memory usage, mutexes are an OS limited resource on some platforms. You could spin lock if mutexes aren't available but the performance characteristics of that are significantly different, which I would expect to hurt predictability. Is the JVM smart enough in all cases to recognize that a

I already have a project that is 90% done and I want to add Cocos2D ONLY to it. I do not need Box2D or Chipmunk. How would I do this? What files do I add? I really need this done, so in the end ill offer a bounty if needed. Thanks! To start the easier way to add Cocos2d into your project is to follow these lines: Import the Cocos2d files into your project like the picture below: Then import the "FontLabel" folder which is located into the "external" folder (Into the Cocos2d library) like the previous step. After, you have to link the OpenGLES and QuartzCore frameworks with your project: Next

I understand that a declaration of a delegate is something like this: public delegate int PerformCalculation(int x, int y); However, there must be more going on. The purpose of the delegate is to provide a pointer to a method, and to do that you encapsulate the reference to the method in the delegate. What kind of structure is this reference held in (internally in the delegate)? I also understand that you can encapsulate a reference to multiple methods in a delegate. Does this mean that there is an array in the delegate that holds these? Also, what methods are defined in the delegate, etc.

I am having problems with calculating CRC-16 implementation of a byte array in java. Basically I am trying to send bytes to a RFID that starts writing to a tag. I can see the checksum value of array by looking tcpdump command on mac. But my goal is to generate it by myself. Here is my byte array which should generate 0xbe,0xd9: byte[] bytes = new byte[]{(byte) 0x55,(byte) 0x08,(byte) 0x68, (byte) 0x14, (byte) 0x93, (byte) 0x01, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x06, (byte) 0x00, (byte) 0x00, (byte) 0x01, (byte) 0x00, (byte) 0x13, (byte) 0x50, (byte) 0x00,
