[boost] Other Pimpl implementation

19 Jan 2006

      Hello,

maybe you are interested in a other Pimpl implementation
which differs from pimpl_ptr in some points.

Here a short overview:

- you could declare a pimpl or inherit a pimpl (usage: pimpl->foo())
- you could also declare/inherit a rimpl (reference to implementation, usage rimpl.foo())
- you could use different smart pointer as pimpl which is adjusted by a policy,
  it's a little bit like a templated pimpl_ptr
- there are more convenient typedefs
- no lazy creation

Example headers:

------------------------
//declare a Pimpl:

class A
{
public:
    A();
    void foo();

private:
    Pimpl<A>::Type d;
};

----------------------
//inherit a Pimpl:

class B : private Pimpl<B>::Owner
{
public:
    B();
    void foo();
};

------------------------
//declare a Rimpl

class C
{
public:
    C();
    void foo();

private:
    Rimpl<C>::Init rinit;
    Rimpl<C>::Type d;
};

------------------------
//inherit a Rimpl:

class D : private Rimpl<D>::Owner
{
public:
    D();
    void foo();
};

The code is at the moment in the loki-lib cvs at sourceforge.
If you are interested I could also send the files.

Cheers,
Peter
