Rich Inside: If I were to implement a pizza ordering system, I would definitely write the code like this, because this kind of code can be written subconsciously without consuming our brains. However, take a closer look at this code: the purpose of this method is to order pizza. However, the code for ordering pizza also needs knowledge about the production of pizza. This method must know all pizza. Worse still, if the types of pizza are to be expanded or pizza with poor sales volume are to be deleted in the future, then the code for ordering pizza will be modified. It looks very bad and should be revised. Our first step must be to separate the code for producing Pizza from the code for ordering pizza, because you should not let the code for ordering Pizza know the logic for producing pizza, but should hand over the logic for producing Pizza to a special type. In this way, we can cope with future changes-if we want to add or delete pizza, we can directly modify the producer of pizza without affecting the logic of ordering pizza. You can click the move command, or click Modify to have a move in the drop-down, or enter M Enter to execute the move command. Class behavior patterns-Use inheritance relationships to allocate behaviors among several classes. Appearance mode focuses on simplifying interfaces and simplifying the dependency relationship between component systems and external client programs.
Five, in the "action" tab of the "block writing palette" click "flip action", AutoCAD? The command window at the bottom prompts "Select Parameter" and clicks the text "Flip State" on the figure (that is, the horizontal mirror axis); The command window then prompts "Select Object" and clicks on all lines and attributes on the graph except the short horizontal line under the triangle (the attribute displays the word "elevation" at this time) and enters. The command window also prompts "Specify Action Position" and drags the mouse to the nearby blank space to click. Strategy mode: Pay attention to the encapsulation algorithm, support the change of algorithm, and replace the algorithm independently of the customer at any time by encapsulating a series of algorithms.
BT in BT investment mode is the abbreviation of build-transfer, which is a kind of rich investment mode created or simplified by Yan Jiehe, a dark horse tycoon on the 2005 Rich List. Compared with BOO (construction-operation-operation) and BOOT (construction-ownership-operation-transfer), BT investment mode has less operation link for the construction party. Its essence is the transformation of BOT (build-operation-transfer) mode, which means that the project management company advances funds to carry out the construction after the general contract, and then transfers the construction to the government department after the construction acceptance is completed. That is to say, advance funds to build infrastructure projects that the Government cannot start for the time being, and then let the Government repay in installments, thus making huge profits.
You can see that PizzaStore depends on a SImpleFactory, which depends on an abstract pizza. Under normal circumstances, to decouple, control inversion is required. The core idea of control inversion is that neither the upper structure nor the lower structure depends on implementation, but on abstraction. Based on BIM technology, it can dynamically display the installation of important parts in advance and provide virtual reality information for construction scheme discussion and technical exchange. Subway construction may have an impact on the surrounding buildings. BIM technology can simulate the impact of subway construction on the surrounding buildings. Combined with reinforcement technology, it can judge whether the arrangement between various components is reasonable, control the construction progress, carry out comprehensive quality inspection and observation on the construction, dynamically simulate the change trend, and put forward improvement measures. MyEvent (sender, e); You may also like: The shortcut key for CAD movement is "M". How to use it: Iterator patterns are created for collection objects, For collection objects, It must involve the addition and deletion of collection elements, and certainly supports the operation of traversing collection elements. If the traversal operation is also placed in the collection object at this time, the collection object will bear too many responsibilities. At this time, the responsibilities can be separated and the traversal of the collection can be placed in another object, which is the iterator object. In real life, there are many intermediary modes, such as QQ game platform, chat room, QQ group and SMS platform, which are all the applications of intermediary modes in real life. Ctrl + K: hyperlink
Above, Interpreter mode: pay attention to encapsulating changes in specific fields, support frequent changes in domain problems, express problems in specific fields into sentences under certain grammatical rules, and then construct an interpreter to interpret such sentences, thus achieving the purpose of solving problems.
Intermediator mode: Pay attention to the interaction between encapsulated objects, and decouple by encapsulating the complex interaction between a series of objects so that they do not need to explicitly refer to each other.
Console.WriteLine (str); The move command is to move the graph to a specified point.
Provides a global access point. Q: How will it be realized? A: Create a static method that returns this class of objects Under the English input method, enter "M", type the space, select the picture block that needs to be moved, type the space, click the left mouse button to start moving, move the required position, and then click the left mouse button. Done. 夜半无人免费观看93动画片 Void Print (string str) Business Innovation Design (STEP 4): To make up for the opportunity gap, business design innovation is required, including developing new products, implementing new business models, adopting new competitive strategies, etc. Business design can help us to design a business model that can seize market opportunities to achieve strategic objectives and the product mix strategy that should be adopted. Market Insight (STEP 3): Closing the performance gap can be achieved by strengthening the implementation of the strategy, while closing the opportunity gap requires new business design. However, the new business design needs to take market opportunities and customer needs as inputs. Market insight is to explore opportunities to achieve future strategic goals. Public class Example 1. You can enter "M" to enter the carriage, or you can directly click the move command button with the mouse to activate the move command. For the operation and maintenance phase, BIM technology can be used to realize virtual reality, asset statistics, space management, building system analysis and disaster emergency simulation. BIM model can improve the efficiency of operation and maintenance, reduce costs, improve the service life of subway and avoid operation and maintenance risks.
In real life, there are paper templates, resume templates, etc. In real life, the concept of template is to give a certain format, and then all other people who use template can implement it according to their own needs. Similarly, the template method is the same.
Decorator mode is also called Wrapper mode, which can dynamically add some additional functions to an object. Decorator mode is more flexible than the way of inheriting and generating subclasses. Although decorator mode can dynamically attach responsibilities to objects, it will also cause some small objects to be generated, increasing the complexity of the system. The specific structure diagram is shown below. 6. Press Ctrl+3? Key, open the "Tools Palette" and drag the created dynamic "Block" graphic to the "My Tools" palette with the mouse. (If you don't have this palette, right-click the status bar of the tool palette, click "New Palette" in the shortcut menu, and name the new palette "My Tools.") First, open Example 1? You can also create a new file by creating and saving the file "My Dynamic Block" in the. Draw an elevation mark in the space according to the size shown in the figure. An event can have many listeners attached to it. These listeners tell the system to call my XXX method when the event occurs by registering their own event handling routines. BIM technology can add time dimension to three-dimensional space model to carry out 4D simulation construction, which is conducive to the optimization of construction period. Based on BIM technology, 4D simulation construction can put forward a virtual construction scheme, which can pre-process various possible induced situations in the construction. The application of BIM technology in the construction stage can reduce possible errors in the process of information transmission and reduce rework. Now, the PizzaStrore (FactoryPizzaStore) is abstract. The CreatePizza method has been migrated back from the simple factory. In PizzaStroe, the CreatePizza method is now abstract.
