modifying the structure of a given object. In object-oriented design, the function extension of a given class is usually implemented through inheritance, however, the adorner pattern does not require subclasses and can dynamically extend functionality as the application runs. 1, a generalized analysis of the production process of dyed steamed bread: (1) The need to produce a normal steamed bun; (2) in order to save costs (not using cornmeal), the us

First, yield generator (yield)Yield is used to end the while loop, and to maintain the state of the previous loop, the next call is executed directly from yield, executes the program after yield, and loops again, and yield can also be used to receive parameters, receive the parameters passed by send (), and assign to a variable.Import time# imports the time module, which is used to give the producer a definition of the duration of the bun, such as whe

Recently, libgdx was used in the project, so I took the time to read opengles, and there was not much information about Android. However, the code pages of opengles platforms are similar, and IOS information is rich, one triangle rotation is found most on the Internet. We recommend some things to learn before learning opengl, on Wikipedia, it is clear that matrix is very important. In opengl, many effects are implemented by matrix changes. The coordinates in opengl are different from those in an

called; This is done only through the __next__ () method, which records the state of the program's operation, and yield is used to generate an iterator function. (can only be called back, not forward or backward, only remember the current state, so the bank's system used to record the use of the yield function). %= %= Consumer (= consumer (i range) runs as follows: A ready to eat steamed buns ... b ready to eat steamed buns ... Bun 1 was eaten by a

processing fast and the consumer processing is slow. Similarly, consumers must wait for producers if their processing power is greater than that of producers. To solve this problem, the producer and consumer models were introduced.What is the producer consumer modelThe producer-consumer model solves the problem of strong coupling between producers and consumers through a container. Producers and consumers do not communicate with each other directly, and through the blocking queue to communicate

During the deployment of the OSPF Route Scheme, the OSPF regions are the most difficult to understand. What are the differences and functions between them? This article will answer your questions one by one. Backbone (Backbone) Region An OSPF network can contain multiple areas, including three common special areas: the Backbone Area and the Stub Area) the non-pure Stub area (NSSA) can also include other sta

equivalent to the producers, customers equal to consumers, customers eat steamed buns, cooks make buns. To make a hypothesis, if the chef to make steamed buns faster than customers eat steamed buns, there is such a situation, the chef and other customers to eat a bun after the next bun (then we say that the chef and the customer's high coupling, that is, cook buns and customers eat steamed buns is closely

First, we know that whether it's creating multiple processes or creating multithreaded pools to solve problems, it takes time to create processes, create threads, and manage transitions between them.Concurrency is implemented based on a single thread, which saves the time it takes to create a thread process.Second, how to achieve the switch between the two functions?def func1 (): Print (1) yield Print (3) yield def Func2 (): = func1 () Next (g) print(2) next (g) pr

This is a simple article about some of the techniques used in JavaScript arrays. We will use different methods to combine/merge two JS arrays, and discuss the pros/cons of each method. Let us first consider the following: Copy Code code as follows: var a = [1, 2, 3, 4, 5, 6, 7, 8, 9]; var b = ["foo", "Bar", "Baz", "Bam", "Bun", "fun"]; It is clear that the simplest combination of results should be: Copy Code code as fo

Java Threading InteractionThreads run independently, but when multiple threads need to access a shared resource simultaneously, a thread's synchronization (synchronized) is used, which is equivalent to a lock on the shared object resource, with only one thread acquiring the object lock at a time. The minimalistSingle example: Sell movie tickets, several windows (threads) at the same time to sell movie tickets, each other threads are mutually exclusive, only one thread at a time to access the mov

keeps the program waiting. The program itself executes the following program. Serial is synchronous, while generator is asynchronous. The generator can continue to execute code from the breakpoint. The generator can save the function interruption status. Purpose: The main effect of yield is that it can interrupt the function and save the interrupt status. After the interruption, the code can continue to be executed. After a while, you can call this function again, run the following statement fr
