class MsgRegistrator from ShapeExtend inherits BasicMsgRegistrator from ShapeExtend

    ---Purpose: Attaches messages to the objects (generic Transient or shape).
    --          The objects of this class are transmitted to the Shape Healing
    --          algorithms so that they could collect messages occurred during
    --          processing.
    --
    --          Messages are added to the Maps (stored as a field) that can be
    --          used, for instance, by Data Exchange processors to attach those
    --          messages to initial file entities.
