In the floating-point sort is sure to use the three-wood operator (the contents of the three-mesh operator to see themselves), because if it is also used in shaping the subtraction of the time if it is two very similar numbers may return a decimal

　　"State Change" modeIn the process of component building, the state of some objects often changes, how to manage these changes effectively? While maintaining the stability of high-level modules? The state change mode provides a solution to this

Http://www.tuicool.com/articles/mQBfQfNObject pooling can significantly improve performance, and if an object is created very time-consuming or expensive, it is very inefficient to create it frequently. Object pooling avoids duplicate creation of
