CGAL::Compact_container_base Class Reference
Compact Container

`#include <CGAL/Compact_container.h>`

## 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.

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