How to port std::vector<MyRect> into mbed?

Hi, I have a standard C++ function that have std::vector<MyRect> allCandidates; .

How to port std::vector<MyRect> into mbed?

Is there similar C++ Vector in mbed?

Thanks, Sung

As long as you have #include <vector> it should work fine, that is a standard part of c++.

Having said that dynamic memory allocation structures like vectors should be avoided if possible on embedded systems, they give quite a performance hit.

Hello Sung,

Assuming that the MyRect user data type is defined in MyRect.h and MyRect.cpp files:

  • Create empty MyRect.h and MyRect.cpp files in your mbed project
  • Copy and paste the code from your original files into the corresponding empty files
  • Include the <vector> and "MyRect.h" header file into your main code
  • Import std namespace
  • Create and use vectors of MyRect type in your project 

#include "mbed.h"
#include "MyRect.h"
#include <vector>

using namespace  std;

int main(void) {
    vector<MyRect>  myVector;
    MyRect myRect(0, 0, 5, 5);

    myVector.push_back(myRect);
    ...
}
