Similarly, in another section, when reading a message, you need to parse it, that is, when you read the data to a fragment, if the data is not a string, you need to convert it to a string. This is done by default when you use the >> operator to read something.
The last thing to give is a very famous, cool trick to use the following code snippet to output the contents of the Streambuf to the console
Streambuf buf; ... Std::cout
Similarly, use the following code snipp
);Func ();}void Service_run () {Service.run ();}int main (int argc, char* argv[]) {Test (Service.wrap (dispatched_func_2));Boost::thread th (Service_run);Boost::this_thread::sleep (boost::p osix_time::millisec (500));Th.join ();}Test (Service.wrap (dispatched_func_2)); Dispatched_ func_2 is packaged to create an functor and pass it to test as a parameter. When test () is called, it distributes call Method 1 and then calls Func (). At this point, you will find that calling Func () and Service.dis
. There are several solutions for the above problem:Use global buffersCreates a buffer and then releases it at the end of the operationUse a Collection object to manage these sockets and other data, such as buffer arraysThe first method is obviously not very good, because we all know that using global variables is bad. Also, what if two instances use the same buffer?Here's the second way implementation:
void on_read (char * ptr, const Boost::system::error_code err, std::size_t read_

by SQL Server's grammatical structure combination. However, if you need to export from this syntax tree to other databases such as Sybase executable SQL statements, it is also in the TSQL class to add a new traversal algorithm, all the relevant code to recompile.
By using the visitor pattern, the algorithm of combining the syntax tree nodes when traversing nodes is encapsulated in the method of the visitor, such as SQL Server's syntax is a Tsqlservervisitor class, and the syntax tree will call
