How to use Loki's Pimpl implementation?

Link to source code of Loki Pimpl hea开发者_运维问答der. I am not able to find any documentation on how to use the same, can any one explain how to use. And what does the following function in the header do.

1. PimplOwner
2. ImplOf
3. PimplOf
4. RimplOf

This page has most of the information you need

Loki has a short smart pointer (Smart Pointer). I use Loki::Pimpl and smart pointer defined as follows:

Loki::Pimpl<string, ConstPropPtr<string> > smartPoint; 

you can try to use this.
