I recently studied boost. Because I have been using a MAC system, I want to study boost on Mac. Because boost is open-source cross-platform, I want to use the Eclipse IDE, because it is also cross-platform. 1. download the latest eclipse + CDT for Mac version. 2. Install the latest gcc48, Sudo port install gcc48 3. Use eclipse to create a C ++ Project, Select cro

Boost: scoped_ptrAlthough it is easy to use, its ability to share ownership is greatly limitedBoost: shared_ptrThis limitation can be solved. As the name implies, boost: shared_ptr is a smart pointer that can share ownership. First, let's look at its basic usage through an example: # Include # Include # Include ClassImplementation{Public:~ Implementation () {STD: cout "Destroying implementation \ n";}Vo

The project needs to parse a SQL statement, and then a variety of Baidu, read some articles, and then dizzy, do not know what they are talking about, it feels like very abstruse. I feel that they speak too professional, not easy to understand. So keep a record of what you're learning so you can see it later.1) to parse a string, first you have to have some rules, such as a string separated by commas, take out a specific string in a string, or a string of integers out, which we call the rules. Th

Condition variableIf there is a dependency on the order of execution between threads, you can use the condition variable (Condition variables).You can use the reference condition variable (Condition variables) in the Boost website.The condition variable must be used in conjunction with the mutex, waiting for the other thread to redo the occurrence of an event (satisfying a condition) before the thread can continue execution.There are two kinds of cond

In the development process, often many people are accustomed to use the new date () to get the current time, it is more convenient to use, but also to get the current time related to all aspects of information, such as get hours, minutes and so on, but also can format the output, contains the information is relatively rich. But sometimes you don't need to get that much information, you just have to care about the number of milliseconds it returns, such as gettime (). In order to get this timesta

details of the appropriate Psyco bindings are found, the acceleration effect is quite obvious. Using the same test cases and training methods provided in the reference article (500 training modes, 1000 training iterations), the neural network training time has been reduced from about 2000 seconds to about 600 seconds-up to 3 times times faster. The number of iterations is reduced to 10, and the speedup is scaled down (but the ability to recognize the neural network is not valid), and the median

Boost's property_tree can be used to read XML files. Use of class boost::p roperty_tree::p tree, which is used to save the parsed XML data stream class, Parse function Read_xml, this function supports FStream and file path two parameters. Getting an XML item depends on the Ptree class that ultimately saves the results of the analysis. If only read the use of the member is basically two ptree.get_child and Ptree.get.

The Boost multi-index containers Library defines Multi_index_container template classes that can be indexed, sorted, and accessed from different dimensions.

implementation Analysis of Boost::asio Io_service the role of Io_service Io_servie implements a task queue, where the task is a function of void (void). Io_servie the two most commonly used interfaces are post and run,post to the task queue, run is the task in the queue until all is finished, and run can be called by n threads. Io_service is a fully thread-safe queue. Interface for Io_servie The interfaces provided are run, Run_one, poll, Poll_one,
