Everyone crossing, welcome to listen to the large-scale couplet science fiction: Vim. Last time we introduced the cscope in the Vim plugin.Last time, we were mainly talking about the plug-in's functionality and how to install the plugin. This time, let's keep talking about the plugin, but we sayis how to use the plugin. Well, still that sentence, gossip Hugh, words return to the positive turn. Let's talk about vim together!Crossing, the steps to use C

precedence is higher for explicit binding and new? Well, because new and call (), apply () cannot be used at the same time, so I did not write the test code between them, but after checking the information, the conclusion is that the new priority is higher than the explicit binding (the great God can give a new priority higher than the actual binding example) ~ If any, please put in a comment , the Little woman thanked ~ ~).That concludes the experience is to judge the this binding rule, First

First, UML diagramSecond, the conceptappearance mode: provides a consistent interface for a set of interfaces in a subsystem that defines a high-level interface that makes this subsystem easier to use.Third, the descriptionQ: When is the appearance mode used?A: divided into three stages :(1) First of all, in the early stages of design , it is necessary to consciously separate the different two layers.(2) Second, in the development phase , subsystems tend to become more and more complex because o

complex business scenarios.Methods of Cyclicbarrier:1. Await () Use this method to cause the current thread to block at the fence point and wait for all threads.2. Await (long timeout, timeunit unit) increases the timeout parameter, and waits for a timeout to throw an exception.3. Getnumberwaiting () returns the number of participants currently waiting at the fence. This method is primarily used for debugging and assertions.4. Getparties () This method can get the number of threads specified in

of T1, because D1 is uninitialized in time, so the default constructor is called when overloaded, and the output of this was is;(b) When creating a T2 object (with parameters), follow these steps:4, executes the constructor of the D1 class Date, because D1 is not initialized in time, so the default constructor is called when overloaded, and the output is the is date.5, executes the constructor of the D2 class date, according to time time (int a):d 2 (a), found that D2 has been initialized to D2

After learning the bubble sort, you will find that this algorithm is constantly comparing exchange. Simple and direct, obviously gives a kind of tedious feeling. Is there any better algorithm? Of course it is, no, it sucks.:-PThis article describes a better-bubbling sorting algorithm: simple selection sortingSee " Choice " The two words estimate also guessed twos. Yes, the idea of this algorithm is that I choose to swap it for the position of the most suitable digit .In doing so, we have greatly

resolve it.When Performance Monitor shows a memory leak, and BoundsChecker cannot detect it, there are two possible: the first, a sporadic memory leak occurred. When you make sure that you use Performance Monitor and use BoundsChecker, the program runs in a consistent environment and operation method. Second, an implicit memory leak occurs. At this point you need to re-examine the design of the program, and then carefully study the performance Monitor recorded counter value of the change graph,

); "[Object Object]"It is clear that this method does not accurately judge that a person is an instance of the person class, but can only be judged with the instanceof operator, as follows:Console.log (person instanceof person);//Output is true3. Determine the native JSON object:var Isnativejson = window. JSON Object.prototype.toString.call (JSON); Console.log (Isnativejson);//The output is "[Object JSON]" indicating that the JSON is native, otherwise not;Note: the Object.prototype.toString ()

is more complex because: Need to handle different node types, very cumbersome A multiple comparison operation is required to move the node down Need to move up to split the 4-node node There are a number of scenarios for splitting 4-node nodes 2-3 Find trees are more complex to implement, and in some cases the balancing operation after insertion may result in reduced efficiency. The improved red-black tree based on the 2-3 find tree is not only more efficient, but also

following notation is only to differentiate semantics), then the identifier STR has the double semantics: first, the type is char* The const address constant whose value is equal to the address of the first element in the array, that is, Str is equivalent to (char* const) str[0]; second is the syntax object that represents the entire str[] array. in sizeof (str), the meaning of STR is str[], so the size of the entire array is returned (this size is determined in the previous array definition),

control.Advantages:(1) The decoration function of the class is removed from the class, so that the original class can be simplified.(2) effectively distinguish the core functions of the class from the decoration function, and can remove the repetitive decoration logic in the related class.Iv. implementation of C + +(1) Conponent is the Concretecomponent class: Here is the person class#ifndef person_h#define person_h#include (2) Decorator and Concretedecorator: Here is finery and its subclasses#

First, UML diagramSecond, the conceptSingleton mode: guarantees that a class has only one instance and provides a global access point to access him. [DP]Usually we can have a global variable that makes an object accessible, but it doesn't prevent you from instantiating multiple objects. One of the best ways is to have the class itself responsible for protecting its only instance. This class ensures that no other instance can be created, and that he can provide a way to access the instance.Third,
