Modules: Allocator

What is it

Has you know the use of malloc with arduino can be tricky. The allocator allow you to create and destroy object without using malloc.

API

class Allocator<T, SIZE> {
      Allocator(); //Create an allocator that create up to SIZE object of type T.
      T* alloc() //Alloc a new object. If there is no more space available retrun NULL.
      void free(T*) //Destroy a previously allocated object. Deleting an invalid pointer causes undefined behaviour.
};

Exemple

#include "aio/Allocator.h"

using namespace aio;

Allocator<int, 20> allocator; //Create the allocator that can create up to 20 int

int* ptr = allocator.alloc(); //Allocate an int from the allocator

allocator.free(ptr); //Destroy the previously allocated int

Warning

• When you create the allocator it automatically allocated the space to store up to SIZE object
