#include <boost/shared_ptr.hpp>

|
|
// This example demonstrates the handle/body idiom (also called pimpl and
|
|
// several other names). It separates the interface (in this header file)
|
|
// from the implementation (in shared_ptr_example2.cpp).
|
|
|
|
// Note that even though example::implementation is an incomplete type in
|
|
// some translation units using this header, shared_ptr< implementation >
|
|
// is still valid because the type is complete where it counts - in the
|
|
// shared_ptr_example2.cpp translation unit where functions requiring a
|
|
// complete type are actually instantiated.
