Structs

A struct is an assembled object that contains variables, functions, or further structs (similar to a C++ class). Members of a struct are individually accessed using the struct name, followed by a '.' and the member name. Example of a counter class that controls a counter and stores it in a file:

#include <gxAPI/fs.h>

struct tCounter
{
  bool tryLoad()
  {
    bool boResult = true;
    try {
      fs.loadFile("counter.dat", this);
    }
    catch(...) {
      boResult = false; 
    }
    return boResult;
  }

  void store() 
  { 
     fs.saveFile("counter.dat", this); 
  }

  void count()
  { 
    ++miValue; 
  }

  int miValue;
};


// We create an object...
tCounter cnt;

// The first time this will return false.
bool boSuccess = cnt.tryLoad();
print(MTR("Load: %success% | Counter Value = %value%") <<  boSuccess << cnt.miValue);
cnt.count();

// Store new counter values.
cnt.store();
