, the call is collected through the Method_missing method and forwarded to the encapsulated object, this process is called dynamic Proxy, in which method_missing embodies the dynamic, forwarding embodies the agent Const_missing method Like Method_missing, there is a const_missing method for constants, and when you reference a nonexistent constant, Ruby passes the constant name as a symbol to the Const_missing method.

strengthen the communication between the team members during the development and to encourage the Po to write a smaller story, we made an attempt a while ago: we tried not to split the task and did it directly after receiving the story, the discussion of task splitting should be postponed from plan meeting to actual code writing to avoid individual operations when writing code. -- In fact, it is very suitable for pair at this time, but unfortunately ....... (A: What is the biggest obstacle for

modified drag-and-drop operation handler: Public void mousedragged (mouseevent e ){Graphics G = getgraphics ();Copy_from_offscreen_buf (g );X1 = E. getx ();Y1 = E. Gety ();Update_buffer (G, new drawitem (x0, y0, X1, Y1 ));G. Dispose ();} Note: In this method, we didn't update the backend buffer. This is because when you drag the mouse, the line is displayed on the drawing board, but the line is not actually painted. so when should I buffer updates in the background? Obviously, when the mouse is

sound of a writing pen on the whiteboard, which I later saw on the whiteboard: When declaring the parameter type, it is best to follow the traditional C ++ Interface Usage unless it is not appropriate: LIf the real parameter needs to be changed, pass a non-const pointer or reference. LIf the real parameter is not changed, pass the reference of the const, or pass the value when the copy overhead is very

The 14th chapter uses UMLBefore exploring the details of UML, we should first talk about when and why to use it. The misuse and misuse of UML has caused too much harm to the software project.14.1 Why ModelingModeling is to figure out whether something is feasible. When models are much cheaper than real entities to build, we use models to study designs.14.1.1 Why build a software modelUML is used when we have some definite things to test, and using UML is less expensive than testing with code. Fo

understand each other's progress, so as to understand the overall progress of the project. (2) give everyone a mental pressure to keep their promises. This is a face-to-head mental stress that confronts the progress of the project. (3) Culture of the team, let everyone realize: I am not alone in the fight, we are a team. so standing meetings can not be replaced by mail, not at the computer, you must look at other members of the eye, not the computer. 2 every day in a fixed time, fixed pl

partition. If you go to a company that uses a partition and compare the company's working environment, you will obviously feel that the frequency and breadth of communication are significantly different. The company provides developers with comfortable seats with handrails and can adjust the height and playback angle to suit different needs of everyone. If you are tired of working at noon, you can lie in a chair and take a nap for a while so that you can put yourself into work in the afternoon.

systems. The overall idea of MOM is that it serves as a message intermediary between the message sender and the message receiver, which provides a completely new level of loose coupling ." "What about JMS?" Cheng xiaopang is a person pursuing perfection. In order to make it easier to understand, he simply moved to a whiteboard and painted it. "JMS is called Java Message Service and is a technical specification for MOM on the Java platform, it aims to

exporting photos from devices to Windows, they often find that there is a problem with the direction of exported photos, it can be either horizontal or upside down. You need to rotate it to make it suitable for viewing.5) gain an in-depth understanding of RunLoop RunLoop is a very basic concept in iOS and OS X development. This article will start with the source code of CFRunLoop and introduce the concept of RunLoop and the underlying implementation principle. Next, we will introduce how Apple

When you want to participate in an interview similar to website development, the interviewer usually asks you to write code on the whiteboard instead of on the computer. So why do you only practice writing code on your computer?

1. When you make a graph, you can imagine that your code is extremely important. We use graphs as a shortcut to understand the code, rather than replacing the code. If you draw a picture but cannot imagine what code it represents, you are building a castle in the air. Stop what you are doing and think about how to convert it into code. Do not draw pictures for purpose. You must always remember that the code is what you want to do. ---Designers evolved from coder, coder experience (code --> repet

number of listeners in AWT. All these listeners are callback methods. In XMLThe callback method is also used to parse XML documents in the parser.The interface is more abstract than the abstract class. Abstract classes must be inherited by subclasses, while Java is a single inheritance. Therefore, abstract classes are restricted. Different interfaces,A class can implement multiple interfaces. It is like the relationship between humans and programmers. It can be said that programmers are subclas

case. Why do you use sketches? Because: Sketch is the most liberal design Free media Any medium that can convey information can be used to make sketch design. Paper, whiteboard, pictures, notes, videos, languages, computers and even "nothing" can be used as a medium, as long as it can express your inspiration. Free space No longer just sitting on a chair, facing a 1440*900 computer screen (even a double screen?). ), in this small window to d
