of the database, and the hardware simply can not keep up with demand. Especially like today's mobile network environment, in the mobile phone there is a relatively simple, comparison of the small software, so it is impossible to do a lot of complex functions, must be in the server domain to do very strong, so as to provide strong features, such as speech recognition on the server to do. This shows that the development of the server in the software industry, become more and more important. How c

// Boost: timer library, used for performance testing and other tasks that require timing. // Boost: timer is not suitable for high-precision time measurement tasks. Its accuracy depends on the operating system or compiler, and it is difficult to achieve cross-platform. // Boost: timer is not suitable for measuring the time span of a large span. The maximum span

Shared_from_this () in a class, you need to pass the shared_ptr of the Class Object to use the shared_from_this function to obtain the shared_ptr pointing to itself. It is a member function of enable_shared_from_this Note that this function can be used only after the shared_ptr A) the following code is incorrect: class D:public boost::enable_shared_from_this The reason is very simple. Although the constructor of enable_shared_from_this B) the followin

Bitset is similar to vector The advantages and disadvantages of vector The appearance of boost. dynamic_bitset just fills the gap between the two. It is similar to the bitset of the standard library and provides a wide range of bitwise operations, and the length is dynamically changeable.Dynamic_bitset is located in the namespace boost. To use the dynamic_bitset component, the header file # Include Using na

Input/output boost. Assign The assign helps to store the values of a sequence into the container. It provides a simple value assignment method by reloading the comma and parentheses operators (operators used for function calls. This library is particularly useful not only for Prototyping-style code, but also for its features, because the code generated by using this library is very readable. You can also use the list_of library to create an anonymou

Math and numerics boost. Integer This library provides a series of functions for the integer type, such as the maximum value and minimum value constant at the time of compilation [3]. The appropriate size type is given based on the required number of digits, static computing base on 2 logarithm and other functions. It also includes some Type Definitions (typedefs) of the standard header file The authors of integer are beman Dawes and daryle Walker.

Function declaration: template Example: // Find_first: [1] searches for the position where the string first appears in the input. // Find_last: [2] locate the last position of the string in the input. // Find_nth: [3] searches for the position where the string appears for the nth time (counted from 0) in the input. // Find_head: [4] Take a string that starts with n characters, equivalent to substr (0, n); // find_tail: [5] returns a string with n characters at the end of a string.

1. ConceptThe range concept is similar to the container concept in STL. An interval provides an iterator that can access elements in [first, one_past_last) of a semi-open interval, and provides information about the number of elements in the interval.1.1 PurposeThe purpose of introducing the range concept is to include many types similar to containers and simplified algorithms for these types.1.2 type usedSimilar to standard containersSTD: pair Built-in array2.

The io_service: Work class can enable the io_service: Run function to not return the result when no task exists until the work object is destroyed. Void test_asio_nowork () {boost: ASIO: io_service Ios; print_debug ("iOS before"); IOs. run (); print_debug ("iOS end");} void test_asio_work () {boost: ASIO: io_service Ios; // Add a work object boost: ASIO :: io_se

1. Overview C ++ 98 provides the string standard class STD: string. it has some member functions that can search for substrings, access characters, and perform basic string processing functions. since STD: String conforms to the container definition, it can also be considered as a sequence container with the element type char (or wchar T), and can be computed using a standard algorithm, however, the standard algorithm is not customized for string processing, and is often "clumsy ".The appearance

required to generate the current offset.For example, the string "122501" is decomposed by offset (2, 2, 4,If breturnpartiallast is true, it is decomposed into 12 25 01.If it is false, it is decomposed into 12 25, and then it ends because there are only 2 Characters and less than 4 characters in the sequence. Example Void test_string_tokenizer () {using namespace boost; // 1. use the default template parameters to create Word Segmentation object

Template Example: Void test_string_join () {using namespace boost: Assign; STD: vector

I. SCOPED_PTRBoost::scoped_ptr and Std::auto_ptr are very similar, a simple smart pointer that ensures that objects are automatically freed after they leave the scope. The following code illustrates the basic application of the pointer: Copy Code code as follows: #include #include #include Class implementation{Public~implementation () {std::cout void Do_something () {std::cout }; void Test (){Boost::scoped_ptrImpl->do_something (

1, VC6 in the Min/max disaster There are some small problems when using the Boost library in VC or other libraries. The min and Max macros are already defined in the header file of Windows, so the two functions in the STL are not called, for example, in MFC, but in boost, it is the std:: function under the namespace, Functions that use Windows cannot accept different types of parameters for use in templates
