pod_veneer Class Template Reference

#include <stlsoft/util/pod_veneer.hpp>

Detailed Description

template<typename T, typename CF, typename DF>
class stlsoft::pod_veneer< T, CF, DF >

Bolts construction and/or destruction to Plain Old Data types.

The parameterisation of this veneer can be used to apply RRID or RAII semantics to a plain old data type. For example,

struct Simple
{
public:
  char *buffer;
};

void Init_Simple(Simple *simple);
void Uninit_Simple(Simple *simple);

struct Simple_Init { void operator ()(Simple *simple) { Init_Simple(simple); } };
struct Simple_Uninit { void operator ()(Simple *simple) { Uninit_Simple(simple); } };

void fn()
{
  typedef   pod_veneer<Simple, Simple_Init, Simple_Uninit>  Simple_raii_t;

  Simple_raii_t simple; // Init_Simple() called here

  . . .

} // Uninit_Simple() called here

Parameters:

	T	The POD type
	CF	The function class applied during construction
	DF	The function class applied during destruction


Public Types
typedef T	value_type
	The value type.
typedef T	pod_type
	The Plain Old Data type.
typedef CF	constructor_function_type
	The constructor function class.
typedef DF	destructor_function_type
	The destructor function class.
typedef pod_veneer< T, CF, DF >	class_type
	The type of the current parameterisation.
Public Member Functions
	pod_veneer ()
	The constructor, within which CF is applied to `this`.
