Description

IStreamPersist introduces two methods, SaveToStream, and LoadFromStreamthat allows the designer to respond a request to store or retrieve the implementing object to a persistent stream.  

You use SaveToStream to serialise an object, and save this data in a stream independent of the running application. This serialised version of the object literally persists and is available for loading back using LoadFromStream. It is then de-serialised, and reconstituted as an object.  

For example, the TGraphic class itself implements the IStreamPersist.
