Detailed Description

template<typename T>
class cadex::Base_Allocator< T >

Implements allocator requirements as defined in ISO C++ Standard 2003, section 20.1.5.

The allocator uses cadex_alloc(), cadex_free(). The allocator can be used with standard containers (std::vector, std::map, etc) to take advantage of CAD Exchanger allocator.

Example of use:

std::list<int, Base_Allocator<int> > aL;
aL.push_back (0);
