allows the bulk of the exception elements from the queue. This API is: int Drainto (COLLECTION Removes a given number of available elements from this queue at most, and adds them to the given collection. int Drainto (COLLECTION Removes all the elements that are available in this queue and adds them to the given collection. Listing 6 describes the process of removing up to a specified number of elements. Because bulk operations requi

Manually developing PHP template engine one (35) The template is called a TPL and mimics the Smarty template engine. The template we're talking about is a Web template, a page written primarily by a language composed of HTML markup, but there's also a way to represent a dynamic generation of content (parsing tags).

Cocos2d-x tutorial (30)-Use of the 1.x physical Engine In Cocos2d-x 2.x, developers can directly use Box2d or chipmunk to simulate the physical world. We have also introduced the use of the Box2d physical engine in 17th tutorials (http://blog.csdn.net/u012945598/article/details/17787243), but the APIs in Box2d are still very complex for developers who are new

design is inseparable from the design of a master loop to repeatedly control the entire game process, of course, the core structure of the game (background phantom control, Genie coordinate change, action frame screen change, etc.) is included in this loop. In the design of a j2-based game, two core classes are required for the program architecture, namely, MIDlet and Displayable. 1. The MIDlet is the main class of j2's. Any program master class must

state change (F;R)->n. For example, let R=1 be the next repetition depth read by F=name.language.country. Its ancestor repeat depth 1 is Name, and its first leaf field is N=name.url. The FSM assembly algorithm details are in Appendix C.If only one subset of the fields needs to be processed, the FSM is simpler. Figure 5 depicts an FSM that reads fields DocId and Name.Language.Country. The output records S1

C-language function pointer statement, I borrowed Pascal's syntax here. We will construct a language that is very similar to Pascal. File structure: The high-level language scripts we will implement are support for multiple files. The scripting engine always needs an external function. In order to allow the host program to provide a declaration of external functions, we made a multiple-file scripting engine
