Detailed Description

template<class T>
class sm_allocator< T >

Provides a way to leverage NX Storage Management (SM) for memory allocation in STL library.

One of the key features of SM is that allocated memory is returned to the Operating System once deallocated. This means that the memory footprint of the application just not increases, but can also decrease significantly.

class MyClass
{
 public:
     MyClass(const std::string& iParameter);
     virtual ~MyClass();
 [...]
};

typedef std::vector< MyClass, sm_allocator<MyClass> > MyClassVector;
[...]
MyClassVector.push_back( MyClassString("InstanceI") );

None of the methods defined in this class is of use to customizers.
