## CGAL::Compact_container_base

### Definition

The class Compact_container_base can be used as a base class for your own type T, so that T can be used directly within Compact_container<T, Allocator>. This class stores a void * pointer only for this purpose, so it may not be the most memory efficient way to achieve this goal. The other ways are to provide in T the necessary member functions so that the template Compact_container_traits<T> works, or to specialize it for the particular type T that you want to use.

#include <CGAL/Compact_container.h>

### Operations

void * | ccb.for_compact_container () const
|  | Returns the pointer necessary for Compact_container_traits<T>.
void * & | ccb.for_compact_container ()
|  | Returns a reference to the pointer necessary for Compact_container_traits<T>.
