ActiveObject

ActiveObject implementation a'la Herb Sutter

Example usage

#include <cstdlib>
#include <functional>
#include <cstdio>
#include <string>
#include "ActiveObject.h"
class Test{
public:
  void Write(std::string data, std::function<void(bool)> cb)
  {
    a.Send(
	     [cb](){
	       // Do job here ( such as write data, whatever)
	       // signal to caller
	       cb(true);
	     });
  }
private:
  morpheus::ActiveObject a;
};

int main()
{
  Test t;
  t.Write("dandy", 
	  [](bool success)
	  {
	    printf("Success: %i\n", success);
	  });
  return EXIT_SUCCESS;
}

Or for async file io ( see testAsyncIO.cc)

    std::string testfilename = "testfile";
    std::string content = "Lorem ipsum dolor sit amet, wisi voluptua contentiones usu et, omittam torquatos dissentiunt no vis. Ei magna clita ornatus duo, oblique dolorum eos et. Pri id prodesset temporibus, mei eu velit graece invenire, veri affert complectitur has te. Ea mea legimus consequuntur, at atomorum senserit sed. Invidunt periculis ius te, at pro alienum quaestio, vim ut verear corrumpit percipitur. Ad pro laboramus intellegat, te cum cibo eloquentiam.\n";

    File::Write(testfilename, content, 
                [testfilename](File::ErrorMsg err)
                {
                    if(!err.empty())
                    {
                        printf("Error: %s\n", err.c_str());
                        return;
                    }
                    for(auto i = 0; i < 5; ++i)
                    {
                        File::Read(testfilename, 
                                   [](File::ErrorMsg err, File::RawData data)
                                   {
                                       if(!err.empty())
                                       {
                                           printf("Error: %s\n", err.c_str());
                                           return;
                                       }
                                       printf("read: %lu bytes\n", data.second);
                                       for(size_t i = 0; i < data.second; ++i)
                                       {
                                           printf("%c", data.first[i]);
                                       }
                                   });
                    }
                });

Prerequisite

tested on linux and windows 10
c++ compiler wich groks c++11 - [g++, clang++ etc]
