significant performance differences for different element numbers.So, theoretically (and theoretically) their algorithmic time complexity is almost "constant" (not if the conflict is to be handled). However, the use of time for the average user may pose a risk. Unless you have a good estimate of the hashing algorithm and the number of elements you are using. In my simple test (using the int element type, the default hash function of STD), the performance of the hash container is ranked at the b

Go Selection of map and Hash_map containers in STLFirst look at Alvin_lee friends to do the analysis, I think it is still very correct, from the perspective of the algorithm to explain the problem between them!In fact, this problem is not only encountered in C + +, but the implementation and selection of standard containers in all other languages are considered. You may feel little impact on the application
In the C ++ language, there are some elements such as arrays, strings, streams, and bitsets that are not part of the standard STL, but are related to STL to some extent. The following is a brief introduction. Array as STL container We know that "dumb" pointers can be good as iterators because they support the required operators. This is not a trivial matter. It means that you can use the regular C ++ array as an STL container and use the element pointer as an iterator by yourself. Of course,

Associated container The so-called associative container is similar to the relational database in concept: each piece of data has a key value and an actual value ). When an element is inserted into a container, the internal mechanism places the element in a specific position based on the key value according to certain rules. Associated containers do not have the so-called head and tail concept (only the maximum element and the minimum element). Theref
About Ext JS components-containers and layout, and extjs ComponentsOverview In the page, the most tricky part is the layout. To achieve the layout, you must have containers that can maintain the layout. It can be said that in the Javascript framework I have tried and used, the layout of Ext JS is the best, thanks to its powerful container class and rich layout class. This article introduces the Ext JS conta
Associative containers)According to the data arrangement in containers, containers can be divided into two types: sequence and associative.The standard STL associated containers are divided into two categories: Set and map, and the derivative et (Multi-key set) and multimap (Multi-key ing table ).

Overview Spring is an open-source framework created to solve the complexity of enterprise application development. Spring books on the bookstore are full of resources, and many articles related to the Internet are well written, there are examples of getting started, solutions for problems, environment settings, source code analysis, and integration of spring with other open source systems. This article introduces the macro Design Concept of spring containers
categories, depending on the servlet container working mode:1) stand-alone servlet containerWhen we use a Java-based Web server, the servlet container exists as part of the Web server. However, most Web servers are not Java-based, so there are two types of servlet containers working in the following mode.2) in-process servlet containerThe servlet container consists of the Web server plug-in and the Java container's implementation of the two parts.

a temporary object, when the function returns, this temporary object will be destroyed, so it is unwise to call the begin () function of the temporary object. In addition, this writing method also has performance problems, because every cycle of Qt needs to re-create a temporary object. Therefore, note that,If you want to use an STL-style traversal tool and traverse the containers that return values, you must first create a copy of the returned value
Original C + + makes a generic container (can hold various types of objects)2014-5-4 Read 494 comments 0If you want an object that can hold all kinds of objects, you can basically say no in C + +, or you can use vectorNow you don't think C + + generics are used, yes, C + + generics are essentially reusing similar code, doing things the same thing, but only dealing with types of differences. This situation is still relatively small, such as vector,queue,map and other
