Member Function Documentation

NewPictureL()

virtual void MPictureFactory::NewPictureL ( TPictureHeader &  aHeader, const CStreamStore &  aDeferredPictureStore  ) const

pure virtual

Interface to the picture restoration process that ensures that a picture of the correct type is restored.

The class of the object to be restored is determined by the UID of the stored picture, contained in the specified picture header.

The function can allow the restoration of:

just one CPicture-derived class, returning an error if the UID indicates that the stored picture is not of the required type

many different CPicture-derived classes, using the UID to choose which of the possible CPicture-derived classes should be instantiated

Parameters

aHeader	The picture header that should be restored.
aDeferredPictureStore	The store in which both the header and picture reside.
