Detailed Description

template<class T, unsigned char pks>
class dal::dynamic_array< T, pks >

Dynamic Array.

Defines the basic container of the library which is dal::dynamic_array<T, pks>. This container is virtually an infinite array of element of type T. When a random acces tab[i] is called, a control is made on i and an allocation is made if needed. The allocation is made by blocks of n elements, where . is an optional parameter assumed to be 5. The structure of this container is similar to the one of std::deque<T> but with a faster random access.

Example of code

If T is any type (with or without trivial constructor/destructor, and with constructor T(0) and T(1)), the following code is valid:

#include<dal_basic.h>
dal::dynamic_array<T> tab;
tab[50] = T(0); // 51 elements in tab.
std::fill(tab.begin(), tab.end(), T(0)); // 51 elements initialized
dal::dynamic_array<T>::iterator it = tab.begin(); 
dal::dynamic_array<T>::iterator ite = it + 50; 
for( ; it != ite; ++it)
  { *it = T(1); } // only the 50 first elements are changed.
