C + + three major libraries boost, Loki, STLportin C + +, the position of the library is very high. Mr. Bjarne Stroustrup, the father of C + +, has repeatedly expressed the view that designing a library to augment functionality is better than designing more grammatical words. In reality, the Library of C + + has a wide variety of problems, and the solution is extremely extensive, from lightweight to heavyweight. A lot of people are eye-opening, or loo

Only one of these is described here, with BOSST parsing.

The result of the replacement is: "Djbh= ' 20021000 ' and FHD like '% Beijing '" Ideas for solving problemsExtract the logical field name from the Advanced filter with a regular expression, and then find the real field name to replace it with the logical field name lookup mapping table. Extracts a logical field name using a regular expression.Use the custom callback function of Regex_replace to find the real field name based on the

about boost Algorithm The boost algorithm is a set of integrated learning Algorithms (ensemble learning) based on the PAC learning theory (probably approximately correct). The fundamental idea is to construct a strong classifier with high accuracy by using several simple weak classifiers, and the PAC learning theory confirms the feasibility of this method. The following comparison of several

Below we will introduce Bitcoin source of the main use of some of the classes, official documents see: HTTP://WWW.BOOST.ORG/DOC/LIBS/1_65_0/, each of these classes also contains a very powerful function, so it is not j

Looking at the information of the Boost.asio Library of the day, it is still a little confused. For ASIO's study to continue, at the same time here also recorded the first small example of their own start. It feels better to start with a small example and then to understand what those principles are. Because the conceptual principle is too abstract, with a small example to know how to be a routine. For the ASIO library in the later study will continue to write some articles to record some notes.

Author: Unknown Source: Internet ithao123Abstract: The IT personnel boost library is a C ++ library that has been thoroughly tested, transplanted, and provided source code. As a backup for the standard library, it is one of the engines of the C ++ standardization process. The boost library was initiated by members of the C ++ Standards Committee working group. It has a significant impact in the C ++ communi

Bind-boost Header file: boost/Bind. HPP BIND is a set of overloaded function templates.Used to bind certain parameters to a function (or function object.The return value of BIND is a function object. Its source file is too long. You can't see it. Here we only write down its usage: 9.1 for common functions Assume that the function fun () is as follows:Void fun (int x, int y ){Cout }Now let's look at how to b

In the Linux GCC environment, boost does not add the-FPIC parameter during compilation. As a result, if a shared library uses the boost static library, the following error is reported:Relocation r_x86_64_32 against 'a local symbol' can not be used when making a shared object; recompile with-FPICIf automake is used for compilation, you can use cppflags to add-FPIC.For boost_000053_0, modify tools/build/v2/to

Boost includes five strings and libraries in the text processing field:[1] Two lexical_cast and format functions are similar to the functions of the C standard library. They focus on the representation of strings and can convert values into strings to precisely format the output.[2] The string_algo Library provides a large number of commonly used string processing functions.[3] tokenizer and xpressive, the former is a word divider, the latter is a fle

Environment: Ubuntu 12.04 32bit, boost 1.49 Preparations: other function libraries are used in boost. To use the functions in boost, you must first install the libraries that may be missing in the system.

Noncopyable Header file: "Boost/utility. HPP" Generally, compilers are good friends of programmers, but they are not always. One of its advantages is that it will automatically provide us with a copy constructor and a value assignment operator, if we decide not to do it ourselves. This may also lead to unpleasant surprises if the class itself does not want to be copied (or assigned a value ). In this case, we need to explicitly tell the users of this

Boost ASIO is a library for Asynchronous Network Communication. Among them, async_write is a common function. However, if it is not used correctly, unexpected potential bugs may occur. For example, the following code: for (int i=0; i The code is simple, that is, loop N times and send n buffer blocks. Our goal is to receive buffer1, buffer2 ,......, Buffer n. However, in fact, the above Code is faulty, and the server may receive completely disordered
